Ci the Nemesis Hound

Imagine a Death Note but... it's a person, and instead of incurring instadeath they have to actually go hunt down the person you tell them to; bound by fate to endlessly pursue their quarry no matter who they may be. Also they turn into huge spikey dog things. That's a Nemesis Hound.

Ci or whatever you want to call her is a big chill dude who smiles to seem less threatening. She's old as balls but doesn't remember most of it, just scars upon scars leaving their history on her body. Her martial skillset is diverse but she prefers a shortsword and sling, and prefers being armoured and less noticable over the use of her dog shape. Her meaty physique and her tendency to gather coin through basic physical labour or mercenary work easily obscures the fact that she's actually very sharp of wit and is usually thinking more than she lets show.

Unusually for a Nemesis Hound, her teeth remain sharp even in human form, so she tries not to show them when she smiles. She smiles often; always best to be friendly, no? Most people assume she is a man, which she isn't particularly bothered by.
