Wyvern: Named after the two-footed dragon of European mythology, these flying nightmares presumably evolved from the order Chiroptera. As with many species of Bat they hunt primarily during the night and sleep during the day, preferring to rest within secluded dark hideaways such as caves or crevasses. When attacking they will swoop down and either scoop their prey up into their mouth or lash out using their rending claws. It is commonly said no man has survived to tell the tale of a Wyvern attack.
Prior to version 0.7, this unit was named the Typhon.
