Black Dragons are warriors. They are strong and capable in battles of force, but also ample magic users, capable of devastating opponents with their spells. Their bright eyes give them excellent night vision, which is why they generally hunt during the night.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Trinitian is known for his stealth, relying heavily on his ability to blend into the night along with his night vision. His name is a homage to his caretaker's late cat Tristian, who was quite similar to Trinitian in appearance and behavior- Choosing to stalk and hunt in the night as opposed to being visible in the day. Trinitian, on the other hand, while much like a domesticated feline in his feeding habits, prefers to hunt primarily for sustenance as opposed to just for fun.

Much like Tristian, Trinitian is fond of chin skritches, hiding in the shadows and scaring others (accidentally..), and bringing back "gifts" for his Caretaker, Including but not limited to: Various Dragons Scales, Horns, Claws and Teeth, Gems, Interesting looking rocks, Colourful leaves, Flowers (Often squished or torn), Patches of Pelt, and Feathers.

His caretaker has a shelf solely dedicated to Trinitian's "gifts".
