Belimarius was the last immortal Runelord of Envy who ruled for many years over his city of Invidia, an integral part of the lost Iskari Empire of Iskandar.

He is believed to have been destroyed, along with the other six Runelords during Skyfall. Belimarius was a specialist in "Envy Magic" (now called Abjuration) and was said to have been a powerful arcane knight.

Like all seven Runelords, Belimarius had a loyal apprentice; Sadrakus. His fate is also unknown.
