Ruin is the ancient Shard of destruction, an immortal force imprisoned at the Well of Ascension who manipulates events for millennia to engineer his own release. In The Hero of Ages he walks free, often wearing the likeness of Vin's dead brother Reen, and wields Hemalurgy and his spike-bound Inquisitors, chief among them Marsh, to bring the world to the brink of annihilation before Vin and Sazed defeat him. Sazed then takes up Ruin's power alongside Preservation's, becoming Harmony. In the later Wax and Wayne era Ruin survives as an ancient god of destruction, a figure of theology and lingering Hemalurgic legacy whose influence still colors Harmony's divided nature.
Description
A tall, broad-shouldered man with a hard, angular face unrelieved by any humor, standing in a straight-backed posture that conveys authority and occasional benevolence. His eyes are distinctly unnatural and piercing, betraying the immortal force controlling the form of Vin's brother Reen, while his mouth can slacken open in moments of blissful pleasure during destruction. He has fair skin, short dark hair, and a powerful build suggesting a lifetime of hardship, dressed in simple dark garments as he gestures with clasped hands behind his back or folded arms. Ancient god figure associated with destruction and Hemalurgy
