Where is Sehwanu?

Anyone find Sehwanu for quest out of the Keys (a ghostly request)? According to GuildWiki, she spawns randomly, but I've now been there over 15 times and she's never there (and yes, I've done the required quests needed to talk to her). Does she spawn at different places in the Keys?

when i looked on wiki... it showed a map of where to find her... and in game she is exactly where the map said she would be.

Yep, been there (and went to that link already, too)--but not seen Sehwanu in over 15 tries. So, maybe someone found her there once, but maybe she moves around

Well, after a few more tries, and after going to mainland, she finally did show up where she was supposed to and I got quest done. Man, too many tries needed to do this one!
