Silver Dragons are arguably one of the most beautiful types of dragons. They live in high altitude habitats such as mountains. Male Silvers hunt and eat meat. While not as beautiful or radiant as females, silver males possess better physical attributes, such as strength.

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.

Cold and aloof, Vergil doesn't really get along with anyone, let alone his younger sister, Dante. In fact, Vergil seems to despise his sister, for some reason, looking down on her loud, messy, and (in his ever-so-humble opinion) uncouth nature with contempt.

Vergil himself is extremely formal and, on the rare occasions he deems to 'speak' with another being, he comes off as highly intelligent and educated...if very condescending and callous. It is noted that his telepathic 'voice' seems to have a faint English accent, for some reason.

The main difference between Vergil and his twin sister is his desire for power, and what he would do to get more (virtually anything, and Heaven have mercy on the poor fool who would dare to get in his way). This has gained him a reputation of being a 'cold-hearted demon' of a dragon, and his sister upholds this, adding in a few choice words of her own.
