What is up with tagging the covenant leader as Quelaag's Sister? While it is true that she is, her name is Quelaan is it not? Shouldn't the name of the tag be changed?
Acording to the wiki page the Chaos Covenant leader, in other words Quelaag's sister, is called Quelaan. Although one could question how accurate the wiki is, it sounds rather legic as the only other sister I have seen mentioned is Quelana, who teaches you Pyromantic spells...
Officially, she's known as Quelaag's sister. Quelaan is a speculation name that we've pretty much started using as though it was official; like Koakuma and Daiyousei, kinda. Some call her Quelaan, some call her Quelaag's sister, but she's not officially known as Quelaan.
I like how everyone is crying over killing Quelaag making her sister lonely. Saying things like "You could've just asked!" Let me share a story to you, in spoiler. There was one knight who has been giving Quelaag's sister humanities secretly. He is Knight Kirk. Joined the Darkwraiths first, then met the blind sister. He joined he Chaos Servant Covenant and used this Darkwraith skills to collect humanities... But because of you... after 3 attempts of getting your humanity... His dark spirit weak... Walks towards the end of the tunnel beside Quelaag's sister and slowly die leaving his armor able to pick up.
And what did we learn? Don't mess with the Chosen Undead. That said, I felt so guilty when I realized what I did. The humanity sacrifice after was worth it. Kirk is a casul at humanity-gathering.
