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.

You can see your kill counts and your rank experience in the quest log.

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.

- This addon introduces a new variant of vault, the bazaar, where you don't fight for items, but rather buy (or steal) them.

- A central aspect of this addon is a new questline (consisting of 3 follow-up-quests), which introduces the player to the bazaar-system. The questline starts in the Village of Elvala (look out for a special npc - he will lookout for you as well).

- I took the idea to this addon from starsapphire (Idea : Markets in dungeons! - http://forums.te4.org/viewtopic.php?f=39&t=42553)

------ Details: ------

(1) Bazaars can appear in most dungeons and outdoor zones, which happen to also generate vaults; chances for regular vault-generation aren't being limited. Bazaars won't appear in the East however - tradesmen haven't made it there yet.

(2) Each bazaar contains a shopkeeper and a limited amount of items, which can't be pickuped by normal means (they are chained to the ground). Instead, you either have to pay to be able to pick up such an item - or you try to unchain it (success chances scale with cunning, dexterity and talent points in Heightened Senses and Stealth). Failure to unchain it will trigger a trap which teleports the player (and his party) to a parallel zone ("Mirrorscape").

--> To escape from the Mirrorscape, a special guardian needs to be killed. Alternatively, there are two hidden exit points. The Power of the Guardian scales extremely with the Base-Level of the Zone (Break-Points: Level 20, 30, 50, 70) and the item-quality the trap is based on (unique items are protected by stronger guardians). Killing the guardian allows the player to pick up the item in question.

--> Killing the shopkeeper unchains all item in his shop. Shopkeepers are extremely strong, however.

(3) Additionally, each shopkeeper has a rare ingredient for sale, and some of them also sell maps, which point to special treasure areas in a variety of zones. To find out about these special goods, chat with the vendor. (Again, treasuremaps point only to zones in the West.)

(4)In Elvala starts a questline, which leads to the discovery of a new zone, The Bazaar. Follow-up quests then introduce more in depth to the bazaar system.

(5) Most bazaar-vaults will also be generated inside the Infinite Dungeon - most Treasuremaps also work here.

(6) From time to time, a caravan will spawn on the overworld map. Encountering a caravan is similar to an "Ambush", however without meeting hostile npcs - instead, two shopkeepers will offer their items.

So, How to start? --> Go to Elvala, talk with a nice dwarf!

Notable modifications to the core game:

- added a new Faction ("Free Traders")
- Overload: added an event zone to Elvala
- Superload: engine/generator/map/roomer.lua - small extension to the code to enable bazaar-vaults to spawn, worldDirectorAI - adding a script for the caravans to spawn
- Hooks: data/talents/misc/npcs, data/talents/misc/objects, data/timed_effects, /data/general/stores/basic, data/general/objects/special-artifacts, /data/general/objects/boss-artifacts.lua, data/general/objects/world-artifacts

Feedback about bugs, improvements, compatibility issues very welcome.

Fixed:
- made vendors "slightly" tougher by giving them a more badass summon and draconic body
- put warnings on treasuremaps, where those lead to very dangerous areas
- fixed an issue with the Infinite Dungeon

24.11.
- Shopkeepers won't get extra talents/classes in higher difficulties anymore (this could lead to errors)
- increased Shopkeepers Life and Resists

27.11
- added more safety-checks to vendors before trying to "return home" after being dislocated, to address a possible error

1.12
- fixed shopguards following the player around while being neutral/friendly
- fixed levelranges to all treasuremaps, which should make them a bit easier on normal and doable on higher difficulties

12.12
- making vendorporting more failsafe (again)
- tuned down a certain lady in the pocket dimension

20.12.

- removed an empty event file from the bazaar main zone, as it would trigger an error with the latest ashes update

01.02.
- items inside bazaars got a new trap. Failing to unchain an items won't upset the vendor anymore, instead the culprit gets cast into an alternate zone, the mirrorscape (much like fearscape)
- caravans spawn from time to time on the worldmap
--> more details inside the updated content text

A warning: you are trapped inside the mirrorscape until you defeat its guardian or find the exit
