Someone in Solas Night-Thorn’s past was killed and he has vowed to avenge their death. Should the object of his vengeance be discovered, he is likely to to do whatever he can to exact revenge, no matter the cost.

Solas Night-Thorn is no greenhorn when it comes to dealing with those who wish him ill. At some point, he managed to cross the wrong people, and now they've got a mark on his hide for it. While such experiences have hardened him for adrenaline-filled moments of evading those who seek to make him their quarry, he can never be quite sure if he is truly safe, for promises of wealth or power can turn even the most seemingly stalwart of allies to enemies with knives poised at his back.

Solas Night-Thorn has had several brushes with madness, and while he may have repressed it, it is ever present in the recesses of his mind. Coupled with his studies into the darker Force arts, he can often be distant and uncaring of others or he could be violent and ruthless. While others may try to resist the temptations of the Dark Side, he has willingly submitted to it.

Solas Night-Thorn has a legendary and virulent need for vengeance. Once crossed, he will make it his life’s work to ensure that whatever slight was received is repaid tenfold. This need for vengeance can be all-consuming, and can often lead to short-sighted decisions.

Solas Night-Thorn utilizes a variant of Form V Djem-So that he has dubbed Shinkage-Ryu. It techniques are based in Djem-So's parries and counters. The technique differs in the grip applied and the target areas. Shinkage-Ryu primarily uses a single-handed grip when blocking or parrying, but switches to a two-handed grip when striking. When attacking Solas Night-Thorn often targets his opponents head and torso with a single powerful strike, following a flurry of strikes.

The form suffers from the same drawback as Djem-So in its stance being too static and lacking mobility. And due to its focus on single strike kills, Shinkage-Ryu is best suited to single combat and can be difficult under the assault of multiple opponents.

Solas Night-Thorn is usually in control of himself in combat. However should he take enough damage, something snaps inside. He taps into the latent madness that exists in his mind and enters into a blood rage. In this state he ignores all pain and injuries, willing to risk everything in order to become a force of destruction that leaves nothing but a trail of bile and gore in his wake. However, his blood rage put him in far more danger than the normal combatant, often resulting in needless injury and suffering, trading safety for pure offensive ability.
