Laguest

A Laguest (also less specifically known as an "elemental") is a primordial creature that forms when a large amount of ethere of one type is concentrated in a place. Not much else is known about the ecology of these beings.

Physical Makeup
Laguests consist of a single core of ethere, generally about the size of a human head and an elemental body that wraps around the core. This is most commonly water, or earth, but other elemental laguests have been documented. The elemental body holds the core in place, and will do everything in its power to keep it from being destroyed. If the core is shattered, the laguest dies.

Powers
Laguests have a wide range of powers based on their type, but all of them have complete mastery over the element they are composed of. A water laguest, for example, can bend, shape, expel, and drain oxygen out of water.

Imperium Laguest
While most Laguests never achieve a grander form than swirling ethere around a prismatic shard, some have been known to become whole beings when properly guided to do so. These Imperium Laguests have the shape of a living being such as a human, or an elf, but can come in many forms. They retain their appearance as elemental beings, but gain intelligence, and in some rare cases, even emotions. Their ethere core becomes something like a heart, pumping ethere (that they must consume on the regular to survive unlike their primordial counterparts), and they store all of their experiences within this core, even after death.
