Lucilla Corrium

Lucilla Corrium is an NPC in The Elder Scrolls: Skyrim. She was the sister of Calixto Corrium. She helped create Calixto's House of Curiosities with her brother. When she died Calixto was devestated and went into seclusion. He descovered ancient magic that could bring back his sister, but he needed marrow, bone, flesh, sinew, and blood. He took to the streets of Windhelm at night, harvesting the ingredients from women. Her new incarnation was being assembled in Hjerim, the house of the first victim. In the quest, "Blood On The Ice" the player stops Calixto from bringing back his sister by killing him or knocking him unconscious.
