Galactic 4th Edition
As FTL travel increased, so too did a number of creatures return…different. They would first go about doing the usual for some time (2d4 days after the jump), though noticeably more aloof. After, they would suffer great pain as they slowly metamorphosed into one of the Changed (chān-jĭd). At that time, they are a new creature, with little to no recognition of their past life.
Many fear the Changed, though no more than they fear Fragments (Shardminds).
Though they do not know it, the Changed are secret spies for the intelligences in the Far Realm.
