Dirtan casts the Silence spell on one of Selvaggio's arrows, after telling the rest, that it will remain in effect for a few minutes, so they should have plenty of time to sneak into position. There is a ruined building close to the temple entrance, which seems an ideal starting point to spring an attack, and the adventurers move into position there, the stealthier ones using their own talents, while the rest relies on the magical silence to get as close to the entrance as possible without being noticed.
Before the temple, they can make out three guards. One of them is a rather old-looking orc with white hair and milky white eyes, who is leaning on a gnarled cane, while the other two are rather big and muscular specimen, both clad in chainmail and holding longspears, which enable them to cover most of the small space in front of the temple.
Anxiously, they await Selvaggio's silenced arrow-shot, the agreed signal to start the attack, which should take care of any alarm shouts.
