Cavern Lurker Dragons are nocturnal ambush predators. Although small, they are very aggressive and will attack anything weak enough to be overpowered. Their preferred method of hunting is to lie in wait in a cave, burrow, or other small, enclosed space; when any potential prey passes they will lunge out to grab hold of the unsuspecting victim and drag it back into the lair. Cavern Lurkers have an odd aversion to sunlight and almost never venture out during the day. More commonly sighted are the odd piles of bones they stack near the entrance to their dens. Their mating call is a low-pitched bumping noise.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Like Manny, another Cavern Lurker dragon in the Separator Territories, Ender is a silent, emotionless follower of other dragons. The only difference between him and Mannifred is that he will actively avoid all hatchlings, even scrambling over himself to get away from them. Ender is also not as stealthy as Manny, and has been spotted attempting to stalk other dragons multiple times.

Ender enjoys annoying the elderly dragons in the Republicator Territories, popping in and out of their caves and just standing behind them. This created a huge disturbance in the Elder Caves once, sending all of the older dragons into a frightful rampage--which ultimately ended with Ender receiving a sprained foot and several kinks in his tail.

Like Manny, Ender resides mainly on the Separator Territories, near the Team Cydragon main cave. He is relatively antisocial in person, and tends to stay away from others--including Mannifred.
