In Dark Souls, the covenant joined at the Undead Parish altar is the Way of White.
The covenant is associated with clerical characters and the established religious order of Lordran. Players can join by speaking with Petrus of Thorolund at Firelink Shrine or by praying at the altar in the Undead Parish after defeating the Bell Gargoyles. The covenant’s original multiplayer purpose is to make members more likely to encounter one another for cooperative play.
The Undead Parish altar is located in the church area below the first bell. This setting links the covenant to the game’s religious imagery and to the clerics who travel to Lordran seeking the Rite of Kindling. The location is also easy to confuse with the nearby mechanism used after the Bell Gargoyles encounter.
The Way of White is not the same as the Warrior of Sunlight. The latter is connected with Solaire, sunlight medals, and a different joining requirement. The Princess Guard is associated with Gwynevere, while Gravelord Servant is led by Nito.
