"Oh good. We do not have a language barrier." Zenyatta clasps his hands before him. If he can continue to ask yes and no questions, they can communicate. Or at least, he can communicate in a crude fashion. He will have to figure out a way for the dragon to communicate to him beyond the blinks.

Zenyatta floats to get a better look at the dragon's sides and above. It doesn't seem like the dragon is fully trapped; it's more of a tight squeeze in a narrow hallway. The dragon needs to go someplace larger.

"I would offer my biome for your use, but it is far too cold. We will have to borrow another habitat until the magic wears off. I will reassure others that you are friendly and ask if we may borrow some space. Does that sound like a plan? Please blink three times if you would like to try this."

And of not... Zenyatta will try to think of another way to help.
