Nexus Dragons are massive, volatile beasts surging with magical power. Each half of a Nexus Dragon’s body is infused with fire or ice mana, and it is believed that the unstable nature of these paired elements drives the dragon mad as it grows in size and strength. They are strict carnivores, preferring to feed on dragons and other creatures that naturally possess magic in order to bolster their own stores. As Nexus Dragons age, fire and ice mana crystals grow all over their bodies, enhancing both their power and viciousness.
Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.
