Xenoron

Xenoron is a mineral that came to Epic from meteors. Xenoron is unable to be broken down by any known methods except for divine destruction, and the reforming of Xenoron is impossible except for divine construction.

Brutus the Berserker used Xenoron to create the Phantom Crusader, and the Crusader's Armor Set.

Xenoron is unaffected by matter manipulation or regular ground enhancing.
