Elan Fluff?

[Kinneus]

I'm considering taking the Elan Heritage feat for a Dark Sun character, but I haven't been able to track down a copy of Psionic Power to read and find out what exactly an Elan is. Can somebody give me the broad strokes of what an Elan is? Specifically, if it is at all appropriate for a Dark Sun campaign?

Elan have been in Dark Sun since 2004, so it should be fine.

Specifically, they're formerly ordinary mortals that have been psionically transformed (by other Elan) into psionic, immortal versions of themselves. They're meant to be an intrinsically psionic, durable race created to fight against aberrations.
