Broken Ouroboros

An old drow fisherman pulls his boat ashore just under a bridge in the Underdark, beginning to prepare a meal. He moves with long, gliding strides across the small shack, ducking his head unnecessarily as if the ceiling were lower. A young drow male, eyes an intense amber, enters the shack carrying a large bag. "Set those right over by the portal, Son. We're eating well this cycle," the fisherman directs.
The young drow lugs the bag under a large painting depicting a burning forest of tall cedar trees, the sky above a tumult of smoke and orange hues from the wildfire. The painting bears numerous scratch marks.
As he moves the bag towards the painting, the old fisherman examines his reflection in a mirror. It shows a fair-skinned being with eyes like pitch-black voids and pointed ears, his expression deadpan neutral, slowly shifting to subtle amusement.
In the mirror, the young drow stands far behind the fisherman, their reflections contrasting. The young drow's reflection remains static, unlike the fisherman's. Upon noticing a dead giant in the fisherman's reflection, the young drow's face twists in horror. He flees the shack instantly, as boisterous cackling emanates from within.
Outside, the amber-eyed drow runs, flames billowing around him, the cackling growing louder. The Underdark morphs violently, resembling a scene of tall, burning trees. As he sprints, the ouroboros torc on his wrist turns into a live snake, tightening painfully. He responds by severing it with a single slice of his dagger, releasing it in a bloody mess from his wrist. With renewed vigor, he sprints faster, the cackles turning more hysterical.
