From publisher blurb:
Nemesis: Not Who They Seem presents five unique NPCs that can serve as adversaries for your unsuspecting players. Each NPC is presented at multiple levels so that they can easily be added to your campaign. Whether you need a quick "replacement" villain because the players dispatched your main bad guy too soon, or you want to add some depth to your setting with side quests and adventures, these five charlatans will serve you well.
Russell Cobbler: A half-elf from a broken home who once dreamed of a life as bard. But the world never cared about his feelings, so now he manipulates the feelings of others to set them up for betrayal.
Lula Harper: The daughter of a noble's servant, Lula learned first hand how cruel and pointless the aristocracy really is. Now she masquerades amongst them in an effort to burn the entire oppressive system to the ground.
Milton the Alchemist: A temporary lapse of judgment sent this skill apothecary down his path of greed. Plying his schemes on those "with more coin than sense," Milton considers his crimes victimless. His victims might disagree.
Charlie Smith: After a horribly fumbled encounter with a green dragon, Charlie ended up with a cursed item that convinced him he was the greatest adventurer of all time. And he'll prove it, regardless of how many companions have to die in the process.
Annaleigh Baker: The former innkeeper's life was destroyed by a necromancer, but her existence didn't end.
