So I assume that being in the light on The First, the special light weather present in all zones with a Light Warden still living, constantly tugs at a person's aetheric equilibrium, nudging it towards the umbral aspect. Emet-selch feels this keenly, because he is almost entirely umbrally astrally aspected, being tempered by Zodiark as others already said.
Just a reminder these are the opposite way around to what we assumed pre-Shadowbringers.
