WARP ENTITY

PHYSIOLOGY
Possibly a gaseous or energy being. It has the ability to "ride piggyback" in the mind of a sentient. It cannot be detected by current medical scanners in it's "dormant" state, but when communicating with it's host a neural surge can be scanned. A manifestation of it is visible when it moves through the tachyon radition around the rift in Sector 14.

PSI ABILITY
The Warp Entity can communicate with a physical host by resonating the  emotional memories of the host. These resonances appear to the host as real events.

HOMEWORLD
Unknown. Possibly on the "other side" of the  space/time warp left in Babylon 4's wake.
