This addon adds in a Faerie, or Fey, race into ToME. This addon was originally created by Kaballah, but he hasn't been online in over a year.
Instead of letting it die (I mean, how could we not be able to play as a Faerie?) I decided to fork it over into a playable form.
I've taken it, modified it's values, and changed it's 4th talent.
You can nab it here.

Dark Faeries are Faeries that have given up much of their natural agility and defense in exchange for bonus offensive potency.
They are extremely frail, even more so than their more agile counterparts, but make up for it with faster offense, higher damage, and many different tricks.
Despite all thoughts otherwise, they are still, mostly, a playful bunch to be around, if not a bit more painful in their method of invitation.

Many in Maj'Eyal have heard of "demons", sadistic creatures who appear seemingly from nowhere, leaving a trail of suffering and destruction whereever they go. Their Fearscape floats far above the skies, watching and waiting, but not idly; their agents scout the land, their legions build up their forces, and their scholars develop new spells and strategies. As the barrier between our worlds begins to crack under their scrutiny, helpless Eyalites have begun to disappear, whisked up to serve as their slaves and playthings. They imbue these victims with magical powers to better survive the ensuing stresses - can you use your new-found abilities to escape the legions of Mal'Rok?

Features:

• Start with a new class, the Doombringer! These avatars of demonic destruction charge into battle with massive two-handed weapons, cutting swaths of firey devastation through hordes of opponents. Armed with flame magic and demonic strength, they delight in fighting against overwhelming odds, softening up the crowd with waves of fire, then feeding on the flames and suffering of their surroundings to stay alive while quickly reducing any group to a pile of ash and gore.
• Unlock a new class, the Demonologist, with an all-new item enhancement mechanic! Bearing a shield and the magic of the Spellblaze itself, these melee-fighting casters can grow demonic seeds from their fallen enemies. Imbue these seeds onto your items to gain a wide array of new talents and passive benefits, and summon the demons within them to fight on your side! Ever looked at a gigantic demon-cursed minotaur and wished it was on your side for once? Well, now you CAN summon one to pound your foes into paste while you cast devastating spells from afar, or call forth a squad of Fire Imps to pelt your enemies to death while they exhaust themselves on your impenetrable defenses! Demons have persistent health, making them a little more precious than disposable necromancer skeletons or summoner beasts, but can be revived from death nonetheless.
• Two new zones, with all-new art, foes, and bosses! You've seen the plains of the Fearscape before, now see the lairs and headquarters of the demons themselves!
• Over 10,000 words of written lore to find! The demons were once an enlightened, peaceful race, hailing from a distant planet known as Mal'Rok; learn what drove them to plot Eyal's eternal torture! Discover monuments to each of the demonic species and noteworthy individuals, showing the place of honor each has among them! Get a glimpse into the culture and daily lives of these sadistic invaders and their brainwashed thralls!
• Unlock a new race, Doomelves: Shalore who've taken to the demonic alterations especially well, corrupting their typical abilities into a darker form. Blink away to safety, transform into a shadowy dúathedlen to hide in the shadows or prey on your foes with blasts of darkness, use your new resilience to soak up status effects and critical hits, and assault your enemies' minds to leave them unsteady in combat!
• Between the aforementioned classes and Doomelves, a whopping 75 new talents!
• Unlock two new cosmetic options! You know you've always wanted demon-horns.
• Two new events, appearing anywhere in Eyal!
• 20 new artifacts, with unique and interesting effects. Collect the Obsidian Treasures to amass more and more power! Slip your hands into the Will of Ul'Gruth and watch your sweeping blows smash down walls! Wear a giant hideous hell-mouth as a fashionable belt!
• 7 new achievements! Conquer the worst Urh'Rok's forces can throw at you, and hang their metaphorical skulls from your profile page!

Donators/Buyers bonus!

Donators/Buyers bonus!

In general, this mod is for people (like me) who like to do everything in a game. Visit all the dungeons, kill all the bosses, preferably get all the artifacts. By allowing all characters to visit some more restricted dungeons, we can make that a little easier. This mod is not intended to be lore-friendly, but I may make a lore-friendlier version in the future. (As it stands you can visit Irkkk as a halfling and the Yeek don't care. I may change that.)

Current mod features:
All characters can visit the Iron Throne, its shops, and its two attendant dungeons.
All characters can travel through the tunnel in the Ancient Halfling Complex to reach the Island of Rel. There they can visit Irkkk and the two dungeons.
All characters will receive caldera at level 20, and sludgenest at level 30.
The maximum level of Rel's dungeons is raised to match Halfling Complex (to 25)
The maximum material level of Rel's dungeons is raised by 1 (from 2 to 3)

v3.7.0 *** FOR ToME v1.3.0+ ONLY ***
If you are using an older version of ToME, visit http://te4.org/games/addons/tome/marson-ui and choose an earlier version of this addon.

An attempt to make 1920x1080 easier on my decaying eyesight, plus a few personal preferences. This is a revamp for the Minimalist UI. It may work for Classic, but hasn't been tested for it. Most settings can be found on the UI tab on the Game Options screen.

• Adds a 'Fonts' tab to 'Game Options'. Choose separate font styles and sizes for six categories:

    * menus & dialogs
    * HUD elements
    * tooltips & character sheet
    * chat & combat log
    * flying text
    * lore

• Expanded font size range to 8 - 36 points. (Stock range is 10 - 18)
• Ability to add your own fonts with a fontpack addon.
http://te4.org/games/addons/tome/font_example
• Scales most dialog boxes to account for larger fonts.
• Hotkey bar revamp:

   * Frame colors: green = activated talent, blue = sustained talent, yellow = equipped item, orange = unequipped item. Colors on talent screen and buff bar changed to match.
   * Frame colors do not change when on cooldown.
   * All talents/items on cooldown will have a red overlay.
   * Z-layer of key text (C8, etc) moved under color overlay to better differentiate from cooldown text.
   * Unequipped items get pale yellow color overlay similar to cooldown overlay.
   * Right-clicking on an item no longer clears the item; it brings up the hotkey assignment menu. (You may clear it from there, as with talents.)

• 'Use Talent' screen now also lists all usable items, allowing you to associate a hotkey using the dropdown menu. Objects are separated based on whether they are worn or not and display their current cooldowns.
• When assigning a hotkey, the list will show available hotkeys as 1 through 0,-,= with C,S,A,AS, modifiers (example: "Hotkey C7") instead of "Hotkey 1" through "Hotkey 60", so as to match the labels on the hotkey bar.
• Enabled and modified 'Creature List' code that was in stock ToME but not used. Lists NPCs in player's sight along with their remaining energy and distance. Mousing over an NPC in the Creature List will center the screen on that creature. Toggle the list on/off with Ctrl-Tab.
• 'Limit Terrain Height' option will rescale trees and mushrooms to prevent them from overlapping the grid above them. (Will not affect current level until you leave and return.)
• Adds viewport options: 'Original' is the stock behavior from v1.1.5 ToME. The game will use Scroll Distance, but won't show a black border around the map. With a high Scroll Distance, you will remain centered until you get to the edge of the map, at which point the map stops moving and your character moves off-center. 'No Hiding' is now the stock behavior of v1.2.x ToME. It is a bit of a hybrid. The map will scroll similar to 1.1.5, but will show enough of a black border so that your avatar will not hide under UI elements such as the mini-map and hotkey bar. 'Centered' will force the viewport to strictly follow the Scroll Distance setting. If you have it a high number, you will be centered 100% of the time.
• Adds option to enable right-click dragging of the viewport. This will coexist with mouse gestures but may not mix with them in a visually pleasing manner.
• Separate adjustable background transparencies for dialogs, tooltips, combat log, chat, and hotkeys.
• Adjustable tooltip width.
• Ability to change tooltip location: each of the four corners / at mouse cursor / opposite corner from mouse.
• Tooltip will get out of the way of target location via keyboard as well as mouse cursor.
• Ability to disable ambient background noises (dogs barking, water dripping, etc.) on the UI tab in Game Options. Defaults to 'enabled' (no change from stock).
• Shields (damage, temporal, etc.) will play a sound when they expire on a character you are controlling. (I've missed that my antimagic shield went down one too many times.) I've included a couple versions of the sound, including silence.

• Adds a choice of tooltip style for the Inventory screen. 'Original' is the same as stock. 'Small Screen' moves the tooltip to either side of the screen so that it obscures less and doesn't bounce around. 'Big Screen' uses a dedicated location between the rag doll and the item list.
• If your character knows the talent 'Extract Gems', a tab will appear on the inventory screen listing all items that may be converted to gems based on your current talent level, including items in the Transmogrification Chest.
• Adds a 'Usable Items' tab to the Inventory screen.
• Adds a 'Preview Talents' button to the character creation screen. This will allow you to view the stats and talents of the current race/class combo without needing to generate a new game.
• Character creation screen will remind you if you are in dev/cheat mode.
• Ability to ESC from character creation screen.
• Alchemist quest shows details about the various rewards you are working towards: "Agrimley the hermit needs your help making an Elixir of Explosive Force, which permanently increase your chance to critically strike with spells by 4%." This will only apply to characters who take the quest after enabling this addon.
(Also available as separate addon.)
• ToME Bugfix: 'Tactical Overlay' dropdown menu.

+ ToME v1.3.0 compatible.

+ Integrated 0player's NPC List speed performance fix.

+ Added frame highlights when mousing over or dragging a hotkey.

Various enhancements to escort quest NPCs:
- Escorts now follow the player when not close to the portal.
- Escorts occasionally say useful things.
- Escorts heal 5% of their maximum health per turn.
