The priestess leads them out the door into the courtyard of the Keep.
A stout dwarf with red hair hails her as she emerges with her flock, "Eadya? Bless my beard! What... how.... where...."
Eadya replies, "Yes Castellan, look here! These brave heroes saved the Temple of Chauntea and guided us through an old tunnel into the Keep."
The dwarf still looks like he isn't fully processing. He is clearly distracted by the siege of the Keep and the small matter of a dragon overhead.
He sizes up the party quickly, "We are in desperate need of heroes this hour! The raiders have breached the main gates over there (he points at the front of the Keep) and that blasted Dragon has nearly blown a hole in the tower (he looks skyward). I can't be in two places at once. Will you help? Its your choice, but decide quickly!"
The party can hear the sounds of wood splintering and metal clashing coming from the front of the Keep.
Chunks of stone fall from the tower above. In the flash of the dragon's lightning breath, the party catches a glimpse of the dragon's silhouette pass overhead.
To the tower to fight the Dragon?
To the gates to fight the Raiders?
Flee! Flee for your lives!
something else?
