And what pray tell, is wrong with providing shelter for this youngster in the Thakrian jailcell? If the Mercinaens and their new friends from Parrius, guard jails with the same vigour that they guard fields and harvest food for their boys on the front
line - then you may as well provide the newbie with a key to the city and an eagle to help him get around...
If it is a regular newbie - it will be smart enough to know that applying guild can get him out of any tight situation instantly. Only real way of dealing with the monster is find an aide to it's city and make him drop stuff with novice force.
