Comfrey

They're a familiar with a powerful witches' coven. When not threatened, or in "rest mode", this character stays present in a simple cat form so as to not draw suspicion to themselves. When in "work mode" or just for their own enjoyment, they can be found in an anthro state, their species now morphed into a tiger so they can better protect the coven. Their horns are a mark of magic, as it is the symbol of their master witch in the coven. Generally a laid-back person, but when push comes to shove, they are a very diligent worker who is advanced in the magick arts. 

As of current, Comfrey's own personal goals are a bit more selfish than his "purpose"; Comfrey wants to be considered an equal and regarded as a witch in their own right.
