Vampire spawn are undead creatures that come into being when vampires slay mortals. Like their creators, spawn remain bound to their coffins and to the soil of their graves.

Vampire spawn appear just as they did in life, although their features are often hardened and feral, with a predatory look.

Vampire spawn speak Common.
