Glaciteron

Glaciteron is a formidable white dragon whose icy scales shimmer like the heart of a glacier, and whose breath carries the soul-freezing chill of the deepest winter. Unlike his white dragon kin, who are often deemed less powerful, Glaciteron's might in ice and cold is unrivaled. His eyes gleam with the piercing blue of frozen fjords, and his presence is heralded by the sharp scent of frost and the howling of blizzards.

Myth tells of Glaciteron as the architect of the Arctic of Palandor, sculpting its icy expanses with gusts of his frost-breath and the beat of his colossal wings. He is a creature born from the first snows of the world, a dragon whose heart beats in tune with the slow, relentless march of glaciers.

The "Rime Genesis" was when Glaciteron's powers reached their zenith, encasing a warring continent in ice and ending a millennia-long conflict by forcing the survivors to unite or perish in the frozen waste.
