Winter White Owl was a pet available during Xmas and Xmas in July events, so it's out there for hatching. I like the wisp idea. I'd like to see the Loremaster's Fonts as pets with possible may cast talents similar to each. Ice with shields and weaks, Life with heals and absorb, Storm with blade and trap.
Since I am , I do like some storm pets. I'm thinking of like a Big Siren, looking exactly like one of the mermaids from when you use the "Sirens" spell.
