The High Priest of the temple has you wait for a while. When he’s back, he hands you a scroll.

-Take this letter with you- he says. -Show it to the guards, and they'll let you enter the fortress. When you are inside, ask to talk to lady Shannon; then offe her your services. If she really has need for a company of adventurers, she’ll speak to you.-

Pocketing the letter, you thank the prior and take your leave.
