Regulus of Hogwarts: Lord of the Stars

"Take your mate and get out." Regulus glanced at the nest. He didn't raise his voice, and he left no room in it either. "I need the place for a while."

Every one of Aragog's eyes went wide, the great pair on top widest of all.

There was no sense in it!

This was its nest, its throne, spun with its own body over decades. It remembered where every load-bearing thread sat. Every spider in this hollow had come from it.

And now this wizard stood in its territory and used that tone, telling it to take its mate and leave?

Its front half reared up, thick forelegs lifting clear of the ground, chelicerae spreading wide to show the dark red inside and the ugly rows of barbs.

Rage climbed up through that enormous body. Offense burned in every eye, and a hiss forced its way out. "That is my nest!"

It pressed half a step forward, eight legs thudding dully on the webbing, and the whole hollow stirred with it, a black tide surging closer.

Regulus didn't react and didn't speak. He looked up at it.
