Thorgal Vol. 23: Thor's Shield

Jolan and his new companions have arrived safely in Manthor's home. However, harmony isn't the word yet, and the instructions from their new master don't help: their next task can only be accomplished if all five of them work together to open a magical gate, but once they're past that obstacle, only one of them can become the Chosen one - and that by stealing no less than Thor's own shield! Can any of them even do it on their own?
