The Darklands are known and feared for the foul abominations which roam these lands, both in the wild and in the captivity of Nocturnian warlords. Perhaps none however invoke more terror than the black wyverns of the Rakarth Mountains. Their numbers are not known but the black wyverns have long been the horror of the surrounding lowlands, where they go to feed on anything unlucky enough to be caught in the open.
The black wyverns are twisted cousins of the noble beasts seen rarely in Avalonia. Because of their size and ferocity, black wyverns have often been the targets of enterprising warlords who wish to use the beasts in battle. This endeavor, of course, carries tremendous danger and has resulted in the deaths of many would-be captors. Black wyverns are not often seen in the front ranks, where they are still vulnerable to enemy arrows and ballista, but instead fly high above to provide commanders with an aerial view of the battlefield. Nocturnian warlords also find the black wyverns useful for interior policing and instilling fear in the border towns of rival commanders.
Black wyverns are extremely powerful beasts and even a bite from their venomous maw can cause death to larger creatures. They are often fitted with simple plates of iron or steel armor to enhance their survivability.
