Yes, playing around with lighting. Alister, being an Evoker (a wizard that can manipulate energy) has a spell which essentially can turn his body into one huge, mobile light.

Also, dragons... in the comic, I had the idea of "dragons" just being a term for these huge, bizarre monsters that collect and hoard knowledge, as well as objects. So their appearances can range from the typical, reptilian dragon appearance to appearances much more bizarre.
