Abyssus was a lonely spirit. Having lived in the darkness his entire life, he had gotten used to having no one to speak to. The spider queen that ruled over the Dark Abyss Spiders was not enough to serve as entertainment. She was rude and lewd, and irritated Abyssus.
After getting bored of interacting with her, Abyssus had retreated into the core of the dungeon where he was born. An unknown amount of time passed as he slept within the familiar embrace of darkness. He slept until he was awakened by a sound that he was vaguely familiar with.
Laughter.
He had heard laughter before whenever the spider queen, Acromantula, mocked his predicament.
'Laughter? How can I hear laughter within the core?' He wondered to himself as he roused himself from his slumber. Peering out of the dungeon core, his vision showed his a clear view of the Core Room from above.
