Wyverns are a race of creatures in Rohbredden. They look a lot like manticores. They have the front half of a lion, 5-fingered hands, wings, and scorpion tails. 5% of them are born mute and use Wyvern Wind Speech. Their visual design may be based on Wyverns from World of Warcraft.
They are asexual and reproduce by randomly laying eggs whenever it seems right.
