6 new familiars now exist, which new conjurers will start to see, bringing the full list of possibilities to:

Good: owl, coyote, faerie dragon, cherub, djinn
Neutral: homonculous, shadowcat, monkey, phase wasp, jann
Evil: imp, quasit, raven, viper, ifrit

A set of 'quest familiars' also now exist for use as quest rewards; generally they're very similar to one of the above, with one or two extra advantages. You may have already seen one or two of these scampering around Thera...

Some credit around the staff where it's due: Adekar came up with a bunch of the new familiars + new powers for them + echoes and stuff. Fjarn wrote descriptions and stuff for the quest familiars. Rayihn also came up with some of the new familiars/abilities.

If you're an existing conjurer, you keep your existing familiar which hasn't changed. We talked a lot about changing some of the existing familiar abilities to try to better balance them but at this point we're still trying to hold back from that.
