"To the north of here there is a large ruin. I think it was once a school, where your kind learned their art. Such a place would have a servant mind, and that might have been told more of why Sucia was abandoned.
"Go there and see if you can learn anything from the servant mind. Be careful, thought. There are rouge creations in there. If there weren't, I could have gone and looked myself." - Learned Pinner
"Search Ruined School" is a mission in Geneforge.
Learned Pinner in Vakkiri asked you to speak to the servant mind in the ruined school. It is north of Vakkiri. Perhaps you can get some clues as to why this island was abandoned.
