Thanks. All the other multi sent me directly to a npc or popped a windows saying a hint like "oh, hmm, may have to go talk to X before i can continue." or bluntly, a npc says : "comme back when youre less puny/more seasoned". I talked to the Eye interrogator since she is the one responsible for Chabon and she didnt say anything.
I had forgot about that anoying Mamora, thanks i'm good to go
