Wuen the vial was passed over to Xerc, he showed no hesitation on drinking it. He took it with a shaky paw and took a small sip, or rather a lick. After that, he coughed a couple of times, not used to the taste. While he pawed at his muzzle, the sense of heaviness disappeared and he felt much more active. He now sat up straight, no longer feeling the side affects of the black substance. 

Suddenly, a strong waft of decay made its way from the girl in black. Xerc shook his head and whined from the horrid smell "Smells like a corpse has been left unburied and is decaying in here." He said, pawing at his nose still. It was rather obvious that he would much rather go through the door than to stay here.
