You actually have to get other people to customize your deer :3 The community is really good at working together, so if your deer is grown (fawns can't keep magic for very long), feel free to ask someone on here to help you get the set you want or go to someone in-Forest and lead them to the spells you want.

You can make friends by being in the Forest often and playing nicely with the other deer, and by being active on the community site here.

An Abiogenesis is when the Twin Gods enter the forest and create wonderful magic shows for the players to enjoy. Here is a video of a recent mini-Abiogenesis.

Abiogenesises used to be scheduled, but since the population of TEF has grown too large for the server to handle us all at once, they are scattered, random, and unannounced until the Abio servers are put online.
