Grace is the hero and title character of Cat's Grace. She is a liontaur bard -- though somewhat small for a liontaur. She escaped from a life of slavery and now looks forward to making it as an adventurer.
Prester is a glowing ball of colored light and Grace's oldest friend. His color changes, so far as Grace can figure, pretty much randomly. His tinkling voice amuses children, since they don't usually understand his snarky asides.
Hope is a half-elf paladin -- noble, kind, pretty, but not too bright. Privately, she longs to seek out new places as an explorer. Her brother is Ray, a druid.
Mark is a good looking (for a half-orc) sorcerer. His memory is often bad. Since he does not remember things very well, he has learned to bluff when questioned. Or to come up with reasonable lies.
