"The Witch of Izalith? Please, do not speak of her. I abandoned my mother and sisters and fled to this land. Now I roam these parts, feigning ablution, and pretending to seek answers."
Now, I've never really thought much about this, but I decided to look into it...ablution is a rather obscure word so I looked it up and this is what merriam-webster had to say about it:
a : the washing of one's body or part of it (as in a religious rite)
b plural : the act or action of bathing
I imagine that the first is what we're looking for...now we obviously know why she would want to wash clean her sins in her involvement of the Dragon Wars, and most likely the creation of the Bed of Chaos...but why would she feign this? Feign, meaning to pretend.
I take this as her not being sorry for what she's done, but rather fears persecution from those who have the power to punish her, and of course, the only one she probably rightfully fears is Velka, goddess who punishes the guilty.
Also, what answers would she PRETEND to seek? Answers to why things are going the way they are? I don't know, but this bit of text makes me not like her much at all.
