Advocate

From fattwiki

Who cheers for a night like tonight? The dark needs an advocate.

The Advocate is a horrible dragon (re)built by the Cult of the Dark Son. Materials used in the construction include a sun, Uklan Tel's starstuff alloy, and the ancient bones of another dragon.

A version of it was originally crafted by Samothes and used to wage war and destruction across Hieron alongside the Solarch in the hopes of spurring on the Heat and the Dark.
