I finally got the first trope-bingo story for this round written, though it became a lot longer than I'd planned.
Title: Impulse Purchase
Fandoms: Blake's 7
Trope: slave fic
Characters: Kerr Avon, Servalan, Dayna Mallanby, Vila Restal, Del Tarrant, Soolin, Nebrox, Benos, Verlis, Cancer, Piri
Length: 2,804 words
Summary: Avon gets sold twice, three slaves get freed, and some get what they deserve. Why yes, the trope being "slave fic", this one's an Assassin AU.
