Petrus of Thorolund

Found in:
Firelink Shrine

Among the ruins up to the right in a room leading towards the Gargoyle church lift. Initially he will not have much to say and then give the player a Copper Coin as a token of good will. Eventually he will ask the player to join the Covenant of the Way of White. If the player says no to the Covenant question, the player can join later (dialogue menu option available) After more dialogue, Petrus will agree to sell miracles.

He may mention an undead mission, and ask for a show of devotion in the form of 100 souls per player soul level. Don't pay him, as he will only describe Kindling, something that will let you kindle a bonfire to Bonfire Level 3 increases the maximum number of Estus Flasks you can carry up to 20.

Story
After the Belfry Gargoyles in the Undead Parish are defeated, Petrus gets a visit from Rhea of Thorolund and two companions from the Thorolund Order in the Firelink Shrine. They are on a secret mission and will not talk much about what is going on. Once the game has been reloaded or the player leaves Firelink Shrine, the visitors are gone and Petrus will not talk much about what happened.

If the player talks to Knight Lautrec of Carim he will offer information to the player for souls based upon summoner level. He tells the player about how the lady and two companions went down to The Catacombs and got attacked, while Petrus escaped and left the others behind. If the player talks to Petrus after this, he will tell his side of the story and about how the lady is left alone and her companions have been turned to hollow.

Talking to Oswald of Carim while a sinner will result in some implications and accusations against Petrus, claiming that his soul is drenched in sin similar to your own. as one can assume that his sin is related to the abandonment of his fellows mentioned by Knight Lautrec of Carim

Tips

 * Killing him gives you 1000 souls and he can drop two humanity.
 * killing him counts as a sin.
 * Killing Petrus prior to Rhea of Thorolund's arrival to Firelink Shrine will cause her and her bodyguards,Vince and Nico of Thorolund, to attack you on sight.
 * Not talking to Petrus at all will result in Rhea and her bodyguards not spawning for the rest of the playthrough.
 * You can take up to 5 Humanities from him via the Dark Hand (NG+)
 * you will find her after Patches kickes you into the pit.(you will save her by talking to her she will move to Undead Parish church)

Tomb of the Giants to help her. (expect a fight from her two hollow gards)
 * if you save rhea and petrus is still alive, he will kill her, make sure to kill him befor going in to
 * I assume that petrus tried to offer rhea to Gravelord Nito in order to join Gravelord Servant covenant, but failed and fled after nico and thorolund defended her, only to fall victims to nito and his servants.
