Sprite

Taking on the appearance of what looks like a flying ball of light, Sprites are creatures that can be seen floating through the facility several times during the game, becoming more and more frequent in later stages of the incident. However, they cannot be harmed and they do not hurt the player in any way. On occasions they even seem to be guiding Adrian. They eventually all lead to the portal that brings the Gene Worm in, evidently acting as energy conduits to construct and charge the gate that connects the two worlds. It is unknown if these are biological aliens or technological creations of Race X.
