At first Cehd'ra wants to protest the detour but realizing what He Ming is after gets him to follow along without complaint. He takes the glass in both hands, going for just a sip as He Ming asks him a question...and then ends up downing the whole glass before he can bring himself to put it down and answer.

"Haa...that was needed." What was the question? Oh, where did the monster go...

"...I believe it went back," Cehd'ra says. "To wherever it was I summoned it from."

Certainly not a plane he was familiar with. That couldn't have been a spirit he shaped like he normally did...he would never shape it into something like that and he hadn't felt that part of the magic go any differently. The best Cehd'ra can guess is that the place he tried to reach wasn't there or he'd missed it somehow. So instead of the raw aether of the spirits he normally called and bound he got something that already had a shape and a purpose...

He thinks.
