Galactic 4th Edition
Myths of Dragons (drag-ŭns) can be heard on nearly every planet hosting sentient life. While the more specific details differ from system to system, each legend refers to them as enormous winged reptilians accompanied with a strange breath weapon.
Strangely enough, stories of such creatures traveling the vacuum of space have been reported. There have been some reports of ships being attacked by such creatures, but survivors are rare and laughed away.
