To understand Aerin it’s important to understand E’lonn; these humanoids live in the seas around Caldera. They have a reputation for being naturally inquisitive and intelligent; this is aided by their long lives – E’lonn can live anywhere from 200 to 300 years. Although they may be found throughout the oceans, they have a central kingdom, ruled over by a king or queen chosen by blood (there are no preferred genders among the E’lonn). Although there are many dangers in the deeps, the capitol is very safe and food is plentiful; for this reason, E’lonn have little understanding of the troubles of surface life. Even the demon invasion and the shattering affected them little.

E’lonn/human relations

Human and E’lonn have interacted for as long as humans have existed; many, in face, believe that humans are the landed descendants of the E’lonn, a theory supported by the fact they they are the only two species able to breed with each other. Although individual attitudes will vary, on the whole, E’lonn are protective of their ‘young cousins’ on land; they see them as inexperienced and all too solemn. They pity the ‘cages of land’ that the humans are bound to, as well as their shortened lifespans. For their part, some humans are infatuated with the E’lonn, and seek to emulate them in deed and culture. Mostly, humans care as much for them as they do any other race, and many humans actively dislike the E’lonn, casting them as capricious, mischievous and alien.

The point of conception

Each Aerin is conceived in a way unique to them. Sometimes their parents know each other and enter into a relationship before conception. More often however, Aerin are a result of a momentary impulse, alcohol, and the adventurousness of youth. This often means that Aerin who grow up on land are usually a member of a single parent household, or even orphaned when they’re born or soon after; some humans see Aerin as a good omen and a people to be cherished, whereas many others only see something unnatural, unnerving or unlucky. Those born into E’lonn society are usually embraced openly, even if only as a curiosity. A vast majority of Aerin are born on the coasts of Lethium, where human and E’lonn societies mix most freely.
