Meet Oozewart, a highly talented, foul-mouthed goblin assassin with a firm aversion to discussing her age. After becoming indebted to a "good-for-nuthin' human" named Lowtrap, she's saddled with a brand new job: Reaper. 

Now, armed with a scythe she barely knows how to hold, she's hurtling through portals and meeting countless new faces... most of whom she wants to punch, and some of whom she's actually supposed to. Her new role, alongside a weird little chap named Wuurrm, is to make sure the multiverse's monsters are exactly where they're supposed to be.
