The strange Doorway to the Red Star lies north of Lake Ocota in the Mwangi Expanse. It consists of a ring of mysterious, humming red stones that hangs in an empty courtyard surrounded by overgrown cathedrals.
Its earliest recorded use was as the headquarters of a nihilistic cult called the Throat-of-Nothingness. Later, it was the stronghold of the King of Biting Ants. The sorcerer was defeated long ago by the legendary Ten Magic Warriors, but the Doorway and the cathedrals were left untouched, by command of Old-Mage Jatembe himself.
Those Mwangi spellcasters who possess the ability to tap into the latent spiritual energies of the ruins of their ancestors say that the Doorway to the Red Star is second only to the Ruins of Kho in potency.
