( I based these dragons off of classic chromatic black dragons, because poison and acid are classic chromatic black dragon attacks.
Now you know why they are a little moody)
Gorebash lands heavily near his consort's lair. He takes note that Slygotha has already cast 'overgrowth' on her swamp plants and created a poison barrier, as well as the acid pool near the entrance. " Something must have upset her" he grumbles to himself. He catches the scent of a female near the entrance to Slygotha's den, then spots her wading through the bog, poking into the den meekly.
Gorebash puffs up, his crest flares, he booms out "and just who are you?"
He prepares to snag her with his claws.

Slygotha calls out from inside her den
"Stay your hand Gorebash. She means no harm to our broodlings. See, your sons and daughters tumble and play on the nest, should you care to enter the den." Slygotha grunts at Eris. Her irises widen a little and her nostrils flare. She has missed her mate, just a little.
