Collan steps out from behind Toruk and suddenly looks different. Dressed in blood-soaked furs with a breastplate made of solid gold and covered with a carving of Pelor's visage within the rays of a sun, he appears as a bloody-handed warpriest. His iron-shod boots look heavy but make little sound as he strides toward the goblins. The heavy steel helmet he wears is covered in blood-tipped spikes arranged to look like the rays of the sun. He neary bears fangs as he opens his mouth to address the goblins.
"Slavemasters! We are here to slaughter your employers! Pledge your allegiance to your new masters and relish in the opportunity to repay the cruelty and disrespect of these orcs with your betrayal against them! So demands The Unstoppable Sun!"
Assuming they like the idea, "Find out everything our new goblin allies know of this place," Collan says to the rest of the party.
