Apeiron are the youngest of the celati species. They are near humans, and each individual has an affinity with one element (air, earth, fire, water) and the humour associated with that element (sanguine, melancholic, choleric, phlegmatic). Apeiron also have 3 genders (with the addition of a neuter one roughly as common as males and females). They regard each other as all being siblings, and even have a psychic bond with one another. Often, when possible, apeiron avoid pairing up with one another, preferring human mates instead.
