Lore & Description

Appearance

Towering and serpentine, the Realmrend Dragon's scales shimmer between obsidian and starlight, as if the night sky itself is woven into its hide. Its eyes burn like collapsing suns, and fractal patterns ripple across its wings whenever it moves. When it breaths, reality itself tears at the seams; the air shimmers, space warps, and distant echoes of unborn futures leak into the present. Its presence corrupts magic and causes time to hiccup, as if the universe momentarily forgot its own rules.

Behavior & Origins

Realmrend Dragons are rare, ancient beings born from the moments when realities diverge. They feed on paradoxes and the fear of collapse, drawing power from the boundary between what is and what could be. Their breath shatters the very fabric of reality, forcing victims to glimpse possibilities that should not exist. They favor lairs perched atop crumbling mountains or in pockets of space where time frays, and they delight in testing adventurers who seek to impose order on a world already bending to unforeseen probabilities.
