All the playthoughs are canon, they are just different timelines
The entire tower is stuck on a
"Groundhog Day" Loop, so all the characters are stuck there for eternity, with no way out... Until Gallus came and end the curse. This explains why you still need to defeat the same set of bosses even after killing them with the other characters.
The characters represent seven sins
- Greed: Obviously Rogue
- Lust: Cultist lusts over power, to the point that she joined the Ashen Cult
- Wrath: Warrior is hell-bent on revenge
- Gluttony: The Adventurer hungers for knowledge about the Silver Eye
- Envy: The mage shadow tells that she feels her sister is a deadweight
- Pride: The spellsword wants to complete of his pilgrimage to and wants to be proud of it
- Sloth: Gallus is accused by Aloysius of cowardice due to lack of willingness to fullfill his duties
