An Excandesco (eks-KAHN-dee-skoh; Lat. "catch fire") is a devil-like Wesen. They are believed to be the basis of the phoenix.
When they woge, Excandescos take the form of a human comprised of jet black igneous rock. They have three digits on their hands and feet. By releasing large amounts of white phosphorus though their skin, Excandescos can generate intense flames. This power can be accessed regardless of if they are woged or not. Due to their nature, they possess a natural resilience to intense heat. They usually take off the majority of their clothes before they woge to avoid burning them.

Wesen (VES-sən; Ger. "a being" or "creature") is a collective term used to describe the creatures visible to the Grimms. They are the basis not only of the fairy tales that the Brothers Grimm have compiled, but also of the many legends and folklore from many cultures (i.e. Anubis, Aswang, Chupacabra, and Wendigo).

Grimms (Ger. "wrath") are specially gifted humans who possess incredible powers, such as being able to see the true form of Wesen even when the Wesen don't want them to. For centuries, Grimms have taken it upon themselves to police and on some occasions, hunt the Wesen population to protect normal humans from the unknown threat around them. As supernaturally-empowered hunters, warriors and arbiters of justice, Grimms are widely feared among the Wesen world and key players in Wesen politics.

Woge (VOH-gə or VOHG; Ger. "a high, powerful wave of water" or "a large undulating mass of something") is the act of changing between human and Wesen form.
As woge is impulse-driven, a dead or unconscious Wesen will usually woge back (or "retract") into human form.

Barso entered the Harrison and Sons store before removing all of his clothes down to his boxer briefs. His hand then lit on fire as he shorted out the circuit breaker. He proceeded to woge into an Excandesco and ignite before he began walking around the store, setting everything in his path on fire. Unbeknownst to him, he killed two employees of the store, Mason Heady and Joan Tapford, who were still inside at the time.
He is an arsonist and a mercenary. He is paid for various missions out of legality, like suppressing proofs, or killing someone.
