Mysterious Winged Creature

This mysterious winged creature can be seen in the Village of Cainus, during one of the many cut-scenes in PDS. It apparently is a peaceful creature. It leaves Edge and Gash alone, flying away, minding its own business. If you think about it, maybe its stomach was just full, from the recent monster ambush that took place just before Edge and Gash arrived, killing all of the inhabitants of the village. If the winged creature's stomach wasn't full, maybe Edge and Gash wouldn't have survived their stay. It's a scary thought to ponder.
