Standing at five feet seven, Teroch is fairly short for his age, yet it is clear that he spends hours a day exercising. There is no fat on his form, and his skin the colour of caramel His hair typically falls black and messy, his eyes dark, but kind. His build is the product of a misspent youth - his muscles compact but clearly evident, his skin virtually unblemished (a sign of his relatively sheltered upbringing, for a mandalorian), and it is immediately evident to a multitude of species that Teroch Erinos is attractive. His expression is rarely without some form of smirk, smile or grin, and the irrepressibly optimistic facade he puts up often buoys the spirits of those around him, whereas his sharp tongue almost never fails to drive those he dislikes away.

He has two piercings in his left ear lobe and another in the helix of his right ear. The two in the left ear are small, black plasteel rings, and the third is a simple stud. The Erinos has a trio of tattoos; the first being on his right shoulder: Sashar’s Mark, given to all of his students upon their being Knighted. On his other shoulder is the Soulfire crest, which he had inked on when he was officially admitted into Soulfire Strike Team. Finally, stretching below his waist-line to almost at his solar plexus is the mark of the di Tenebrous; a tattoo given to all members of the Arconae. The swirling, vaguely sun-like pattern is horizontally cut by a large lightsaber scar, neatly bisecting the mark. Teroch has opted not to have the scar removed, as he felt it symbolises his relationship with the clan perfectly.

In terms of attire, he prefers low-slung baggy pants made from a durable material with a myriad of pockets, heavy combat boots and his main concession to mandalorian armour – a sleeveless mail vest. He also often accompanies this with a nerf-hide coat a few sizes too large for him (given that it belonged to his father, Voden) and a pair of fingerless leather gloves to give him added grip with his various and sundry weapons. He also eschews fashion in favour of a pair of well worn and scuffed combat boots. He is never seen without a small silver pendant about his neck shaped like a vial attached to a black metal chain. The pendant contains a very small amount of Sashar’s blood contained within. situated along the chain’s length are numerous barabel teeth, given to him by his former apprentice, S’nar. These teeth once belonged to the Barabel cult leader of the Death Walkers, who hunted Teroch through the bowels of the Citadel when he was a child.
