Sigar

Sigar is a Nord encountered at random locations. He stands by a dead High Elf and has offered the player, who he addresses as the Champion of Namira, to feed first. It is likely that he will only have this dialogue after the player has completed The Taste of Death and has gotten the Ring of Namira. If you completed The Taste of Death by killing Eola and the cannibals by saving Brother Verulus then Sigar is hostile to you instead.

He is simialr to the Madwoman in the way that they are both random encounters and are both related to Daedric quests.
