The guardian of the Empire's capital is MYZRAEL. Myzrael was sent to aid the human Empire in their holy quest. He guards the human capital against enemy invaders, never leaving it unprotected

The Empire's capital - D1

The Empire's capital - D2

In Dark Prophecy and the expansions, a captured capital crumbles into ruins.

In Guardians of the Light, the backgrounds are different from Dark Prophecy and there is a different background for each capital. They are real nice. Try to capture a capital, if only once, just for the ambiance.
