As of the relaunch of servers this morning, character creation is avail on Gilgamesh. How long though is the question, as we're still waiting on all the details of the patch. There were 3 new worlds added, one for each region, as well we're assuming new servers for each existing world to increase capacity have also been added on the backend.
If you're awake, come make a char asap, just in case they become full again!
