Sin Seer is the only female seer. She can be found on the second floor of the building with the spinning wheel in Seers' Village. She is consulted during The General's Shadow miniquest. She seems to be holding some sort of staff that has a carving of a bird with rubies for eyes and a beak that makes it look a little like a scythe. It also seems to help her stand as she has a hunch. She's also slightly crazy and (if not doing the miniquest) will say "Augh! Your sins! They BLIND me!"
Her name is a play on the word sincere, in which her examine text is related to.
On 23 January2010, after the Strange Power spoiler update she was heard saying, "My inner eye is clouded from the wave of darkness; give me a moment." The dialogue box expressed the confused/drunk/dizzy animation during this comment until you continued to speak to her, where she would then ask, "What do you want?"
There is currently a glitch that causes her arms and back to stretch toward the floor behind her. This has not been fixed.
