Sword of Caine is an expansion set for Vampire: The Eternal Struggle, published by White Wolf in 2007. It focuses on the Sabbat, specifically the Black Hand, and functions as a companion to the similarly Sabbat-focused Third Edition (and Third Edition's introductory Player's Kit). All 60 cards in this expansion are new cards, and the set was only published in booster packs with no preconstructed starter decks.
