Blackspawn collectively refers to a group of creatures that are occasionally born to chromatic dragons of that colour after their eggs are imbued with the divine essence of Tiamat, the queen and mother of all their evil kind.
Blackspawn raiders are the smallest of them, bipedal creatures with the tough scales of a larger dragon. They fight in clannish packs, and are skilled at stealth and infiltration, but powerful close combatants with their falchions and many potions. They can also periodically breath lines of acid, and coordinate their attacks with one another carefully.
The dragon Darkhorn was guarded by a group of blackspawn led by a ninja called Sarvas.
