It holds an enormous scythe in its bony hands. \n'b' Underworld sentinels are undead giants sworn to serve the gods of death and undeath. They stand guard over necropolises, cemeteries, and the subterranean temples of the ghoul gods. \n'b' Others watch over the entrances to the realms of the dead beneath the earth, charged with stopping the inhabitants from leaving\xe2\x80\x94or the living from entering in the hope of rescuing the spirit of a loved one. Whatever their orders, underworld sentinels remain steadfast in their devotion to their dark gods and unswerving in their resolve to defend their posts. \n'b'  Dark Origins . Centuries ago, a sinister cult dedicated to the deity of death arose among a clan of deep-dwelling stone giants. Heeding the pronouncements of a herald of undeath, the giants gave up their natural lives in exchange for immortality and unholy power. Carving runes and symbols into their bodies in a dark ritual, they were transformed into the first underworld sentinels. In the many years that followed, underworld sentinels spread throughout the world. Some enter the service of liches or mummy lords as guardians, while others dedicate themselves to protecting a shrine or temple to a deity of death or undeath.'
