The Lost Sinner is the Witch of Izalith and the insectoid creature that crawls into her eye is the same thing that controlled the Bed of Chaos. If you don't believe me, compare the pictures of the creatures. Shalquoir even states that The Lost Sinner is being self-punished for failing to recreate the First Flame. If you have played Dark Souls, the Witch of Izalith attempted to recreate the First Flame but instead created the Chaos Demons and sentenced herself to eternal punishment for her sins. Now, some argue that it can't be the Witch because you defeat the Lost Sinner in the game and absorb her soul. I believe that at some point, the player character eventually has these great souls removed and they are manifested in other forms. The Lost Sinner (the Witch of Izalith) is manifested as the creature you see in Dark Souls I; the Iron King becomes Gwyn, Lord of Cinder; The Rotten becomes Gravelord Nito or vice versa; The Duke's Dear Freja is the manifestation of Seath the Scaleless' soul. And as stated in the games, time is warped so this is entirely likely.
