Kain is a powerful skeleton found in the Battlehorn Castle Grotto. He wields an enchanted, leveled weapon called the Dragonsword of Lainlyn, along with Lord Kain's Shield. He is only found in the Fighter's Stronghold official plug-in.
Lord Kain was originally the leader of the Knights of the True Horn before falling in battle against Baron Shrike of Lainlyn, the True Horn's enemy. After his death, he was almost resurrected by the necromancer Arielle Jurard, but she failed, resulting in Kain being turned into a Skeleton Hero.
- Lord Kain was actually brothers with Baron Shrike, but wanted to end his reign over Lainlyn. He was also brothers with Lord Harth, another commander of the True Horn who also wanted to remove Baron as ruler.
- His original name was meant to be Lord Khain.
- He was mentioned in The Elder Scrolls II: Daggerfall, but never appeared in the game. He is just known as one of the political factors that existed.
- Kain's backstory is similar to that of Kain, the main protagonist of the Silicon Knights/Crystal Dynamics Legacy of Kain series, who is a nobleman resurrected by the Necromancer Mortanius.
