Dawn

Lensig, also known under her alias "Dawn", is a witch who features in The Death of Chivalry. She pretends to be a sister of the Abbey of St. Elspeth Citharede. She told the player  that the Black Knights have found a weapon sealed behind a holy barrier, and they're trying to sacrifice her to breach the barrier. She remains behind when Sir Owen and the player finds the wand. However, it turned out that she was a Zamorakian mage when she stole the Elora's wand after being unsealed by the player. She then casts a magic spell at Sir Owen corrupting him and raise the fallen black knights into the undeads, attacking the player.
