Aetheric Elan often live for a couple of centuries or more in the Aethres, and they typically only incarnate when four or more of them agree to band together and use their power to manifest a body in the material realm which one can occupy. They emerge from this process as fully-formed adult-sized humanoid beings, approximating roughly a 20-year-old human adult. They can survive this way for up to fifty years if they truly had to, aging as a human would, although no Elan would choose to stay incarnated for so long without a very distinct purpose in doing so.

Elan are possessed of one drive amongst all others, and that is the pursuit of knowledge. They are all meticulous researchers, and they favor organization and structure. In terms of morality, however, many Elan are almost aloof to concepts such as good or evil, and they may even scorn such scruples as antithetical to the pursuit of unbiased knowledge. As such, most Elan are Lawful Neutral.

The incarnated form of the Elan is either male or female equally, depending usually on the gender reference the Elan prefers for the incarnating experience. They stand five feet tall and weight around 125 pounds, as a medium size creature.

Elan base land speed is 30 ft.

You emit bright light of any one color from your eyes and mouth within 10 ft, and dim light for 10 feet beyond. Closing your eyes negates this light until your eyes are open again. Additionally, your inhuman nature makes sleep unnecessary, and as such, you do not need to sleep, but merely spend 6 unbroken hours in light activity to gain the benefits of a long rest. Bafflingly however, Embodied Elan can still choose to sleep, and spells and effects that would put them to sleep affect them normally.

You awaken to your psionic potential, which enhances your mind. You also harbor a wellspring of psionic power within yourself, an energy that ebbs and flows as you channel it in various ways. This power is represented by your Psionic Talent die, the starting size of which is a d6.

Psionic Talent Options. You can use your Psionic Talent die in the following ways:

Psi-Boosted Ability. When you make an Intelligence ability check, you can roll your Psionic Talent die and add the number rolled to the check. You can choose to do so before or after rolling the d20, but before you know whether the check succeeded or failed.

Psi-Guided Strike. Once on each of your turns when you hit with an Intelligence attack roll, you can roll your Psionic Talent die after you make the damage roll and then replace one of the damage dice with the number rolled on the Psionic Talent die.

Changing the Die’s Size. If you roll the highest number on your Psionic Talent die, it decreases by one die size after the roll. This represents you burning through your psionic energy. For example, if the die is a d6 and you roll a 6, it becomes a d4. If it’s a d4 and you roll a 4, it becomes unusable until you finish a long rest. Conversely, if you roll a 1 on your Psionic Talent die, it increases by one die size after the roll, up to its starting size. This represents you conserving psionic energy for later use. For example, if you roll a 1 on a d4, the die then becomes a d6.

Whenever you finish a long rest, your Psionic Talent die resets to its starting size. When you reach certain levels, the starting size of your Psionic Talent die increases: at 5th level (d8), 11th level (d10), and 17th level (d12). If you have a Psionic Talent die from another source, such as a class feature, you don’t get more than one die; use only the one with the largest starting size.

Psi Replenishment. As a bonus action, you can calm your mind for a moment and restore your Psionic Talent die to its starting size. You then can’t use Psi Replenishment again until you finish a long rest.

Even amidst others who may eventually open their mind to psionic power, Elans are virtually composed of the stuff, and thus are far more capable than other psionic practitioners. You gain your choice of either the Telekinetic or the Telepathic feats.

Additionally, an Elan's willpower is always resolute and firm, making you much more difficult to influence with mental spells. You have advantage on saving throws against Divination and Enchantment spells.

Embodied Elan do not live and die in the same sense as other mortal beings on the material plane, but their incarnated bodies can still be destroyed. When an Embodied Elan fails its final death saving throw and would die, its true form bursts from the body in a flash of colored light and is immediately drawn back into the Aethres. The body dissipates into ectoplasm, and the Elan consciousness returns to it's home realm in the Aethres, often reeling in pain. No magical form of resurrection or returning the dead to life will bring them back to their previous state. Only a Wish spell, a True Resurrection spell or another special ritual manifestation of a group of four or more Elan can recreate the physical body that an Elan can embody into.
