Point Zero is the headquarters of the Keepers of Reality, a faction of chronomancers. Point Zero resides at the nexus at the beginning of all the threads of time. (Time travel was made possible by the Spellblaze; it is not possible to travel back any further than that.)
Point Zero has a scaling level range of 1 to 15, and a maximum material tier of 2. Store inventories are generated for level 8 at character birth, level 25 after The Master, and level 40 after the Charred Scar.
Chronomancers of certain races will begin here, but will be sent almost immediately on their first quest, in the Unhallowed Morass. After the player returns from there, the town will be attacked.
Point Zero contains a (one-way) portal to Maj'Eyal. Chronomancer characters who begin in Point Zero will also receive a talent allowing them to return to Point Zero.
