Thunder Dome I simply wander around you

Having been a loner his whole life — bar his early childhood which he could hardly remember — Noctura was more than used to sleeping in a den that was far from homey. It was rarely even a den, in fact. But the truth was, despite not yet finding any caverns within the mountain, Noctura had spent the night very comfortably at Thunder Dome so far, resting beneath the great protective bow of an ancient evergreen. He would have slept soundly if it hadn't been for the quiet paranoia ever digging at the back of his head. Paranoia that coming here had been a mistake.

So when Asterr spoke of a cavern within the mountain, his mind did not leap to the idea of shelter or comfort. Instead, gazing down at his leader's youthful face, he imagined what magic might lie within. A forest within a mountain? he clarified, soft awe in his deep voice. I'd certainly like to see it. There was no doubt in that whatsoever. He had never encountered such a phenomenon in all his travels.

And if Asterr would join him in this adventure, the unlikeliness would be more magical still.
