From publisher blurb:
The trusty mount that you ride into the heat of battle!
The fierce wolf you raised from a cub and fights at your side!
The watchful eagle that acts as your eyes and ears in the field!
The fancy emu you hide behind?!
Animal companions follow you on your journey, providing a unique bond as they back you up in the wild places you find yourself in.
