Trinitum
Trinitium, also called holy metal or the blessed alloy was a divine material created by the hand of The Creator Himself.
Trinitium weaponry and armour was wielded by the Angels. Trinitium never rusted, and blood never stuck to it. It appeared to be like a more saturated gold, and was so reflective that it often looked like it was glowing.
As a supernatural material, it was exempt from the laws of physics and the arcane. For most mortal creatures, trinitium was too heavy to be picked up. However, particularly righteous individuals, including Angels, could not only pick up trinitium, but also use it to conjure the fires of Heaven. If an evil creature attempted to use trinitium, they risked being incinerated on the spot.
