Appearance-wise, they look very much like some sort of hairless feline standing upright on two legs. Though this is not quite a full description, as they are not entirely animalistic in their appearance. They bear all the hallmarks of beings evolved from a more bestial creature, in the same way, humans have from apes.

They are blessed with an innate Pyonic ability. Giving them the power to perform minor feats such as moving small objects with their minds or even seeing into the possible future. But it is their ability to channel their powers into their unseen eye present in their ears that is the most powerful. Using this, they are able to see all that is there to be seen aside from the most obtuse of things.   Svex share a lot of similarities with humans in both biology and culture, including many of their more unfortunate tendencies.   Svex often appear in other worlds, though some inexplicable means or another.

Svex in Ulltwhaygon

Svex in Ullthwaygon hail from the waistline of the world, where they still hold their largest city around the Black Iron monolith that the legends say brought them here.

Svex in Other Worlds

Svex can appear in other worlds much as they have in this one. From great crashed structures from beyond the skies and stars. This could very much be extended to interdimensional travel as well. When stripped of their more fantastical abilities, Svex function very well as a somewhat plausible alien species for more grounded fantasy or sci-fi settings.
