Ah the Giant Bat. Quite a fearsome creature standing at 10 feet tall at the shoulders when on all fours and a wingspan of 60 feet. It will feed on any creature it can carry away be it horse, cattle or humanoid. Despite this or perhaps because of it, it is still sought after as a mount. One must be very brave or very insane to attempt training or riding one found in the wild. Raised from youth though, training the creature is quite possible.
