Ramuthra (also called the Great Terror or the Greatest Monster) was the leader of demons during the Wars of Liberation in Fedeledland. He was once much more powerful than what he is now, as he was almost killed by the joint attack by the demonic rebels (under Grendel's command) and the Fedeledlandese rebels (under Stórrekkr the Great's command). It is not known if he has already cured or not, as Ramuthra hasn't been summoned since he was expulsed from this Earth at the end of the Wars of Liberation.
