An eidolon in 2265.

An eidolon was a humanoid Devidian, found among the senior ranks of the Devidians. The eidolon levitated above the ground, only touching down occasionally, and was the more experienced counterpart of the umbral. (STO - Spectres mission: "What Lies Beneath")

Appearance and specificationsEdit

The eidolon shared the majority of its bony appearance with other Devidian ranks but exhibited a taller frame, and stood apart thanks to the tower-like extension of its head. The face was dominated by a maw-like orifice on the forehead. Visitors did not speak during encounters in their natural form. (STO - Spectres mission: "What Lies Beneath")

Eidolons shared most of their abilities with the umbral and visitor. Both varieties were weaker than eidolons. An eidolon's strength was equivalent to the commander-level compared to officers in the Alpha Quadrant Alliance. (STO - Spectres missions: "Skirmish", "What Lies Beneath")

The eidolon did not bear visible arms, but could fire a spectral blast, which sent bolts of psionic energy at a target, ignoring the target's personal shields. After taking damage, umbrals would phase-shift, which increased the strength of their abilities but lowered their resistance to proton-based damage. Another ability was exhibited in the draining of neural energy, by holding a victim and absorbing their neural energy. The ability to propel themselves towards an opponent and deal physical damage on impact was called wrathful surge. While the eidolon shared these skills with the lower Devidian ranks, an ability unique to its position was the spectral essence reflection, which allowed an eidolon to drain an opponent's life-force and transfer it to an ally to heal it.

In the year 2409, an Allied away team fought Devidians in the lower levels of Ferengi-owned Drozana Station. The triolic energy had degraded the maintenance hologram Gein, turning him homicidal. A Devidian portal formed the heart of a Devidian nest, and was found to lead to the year 2265. (STO - Spectres mission: "What Lies Beneath")

Using the portal, the away team exposed Devidians near the command center of 2265 Drozana Station, then an active Federation starbase. After eliminating these, the away team returned uptime. (STO - Spectres mission: "Everything Old is New")

Travelling back to 2265 by slingshotting around Bepi 113 with their starship, the Allies defended the residents and guests of Drozana Station's bar against attacking Devidians and defeated their leader, the Shrouded Phantasm. To put an end to the Devidian incursions to this point in time, the Allied starship destroyed the nearby source of triolic energy, Driffen's Comet, and returned to their present. (STO - Spectres mission: "Night of the Comet")

Using a triolic pattern enhancer by AQA officers could cause an eidolon to appear. (STO - Spectres mission: "What Lies Beneath")

From 2410 onwards, AQA officers practised ground combat against Alliance and non-Alliance forces in the holographic arena event on Qo'noS, the qaD HoS, or Arena of Sompek. (STO - Iconian War mission: "Arena of Sompek")
