My theory on Petrus is that he originally was sent to Lordran as a guide to all Undead sent on their mission for Kindling. However, he got sick of that mission and he began hunting them. Think about all the gear located near Petrus in that secret stash: Lloyd's Talismans, Cracked Red Eye Orbs, a Morning Star(weapon of Petrus), a Talisman(also a weapon of Petrus), and then some Homeward Bones(which are actually irrelevant).
