implemented the dialog with Aslona emissary, so it is now possible to properly start the quest.
also, having the stupid encrypted scroll with you after accepting the quest doesn't seem right to me. so the player now asks the emissary if he can read what is written in the scroll, and the emissary takes the scroll away, promising to send it to Aslona wizard to decipher. this way the player will know for sure that Petrus' quest is no more.
now i have to implement "not on the same continent" flag for POIs.
