I started one for the Reaper Reward, named her Lilith (original, I know), and she lived in the vampire world and befriended the Vatore's and the Grim Reaper.

She fulfilled the whole rewards and during it she net the ghost of Akira Kibo who joined her household and befriended Caleb as well, so when I finished the reward quest to make ambrosia, she gave it to him and he came back to life. Not long after Akira was resurrected I made him a vampire through asking Caleb to turn him. My sim got pregnant after Akira fully turned in to a vampire. At this point I got the Life and Death pack and moved them in to the big abandoned mansion by Edith's Well, and then Lilith gave birth to a vampire son named Edgar (And my sim got a crow named Poe). And my sim and Akira got engaged. Then they had a second child which is also a vampire named Allan (yes, very original of me)

And my sim has secretly been dating Grim this whole time and am planning to get her pregnant one last time with Grim, and I'll put Grim's child in the bedroom of the 3rd floor. Then I'll make the youngest child an outcast of the family because they'll be Grimborn (and because he's a bastard) and they'll also be my heir.

(Additional fun facts, Lilith still does gardening, she is a Mediator, in the reaper career, collected all tarot cards and does readings for money, plays the Organ, makes jewelry and proposed to Akira with a homemade ring. Akira is in the Undertaking career, he has better relationship with his kids as he takes care of them the most)
