Souls of humans were researched and weaponized to augment the Angelic Host. Phantoms abducted humans in the night, as part of a process of gauging Sanctuary's defenses. The Reapers were active on Sanctuary two months of Diablo's defeat at the Crystal Arch. Those of his servants who found him in Pandemonium never returned to Heaven, and gathered to his side. Malthael departed Heaven after the destruction of the Worldstone. They cast away wisdom and gather in his shadow.' 'Malthael's servants are looking for him, but those who find the archangel in Pandemonium never return to the Heavens. The majority of angelic Reapers either lose their wings, or display the skeletal and gray remnants of them. Many of the angels in Reaper ranks are very similar to regular angels, but some (like Ghastly Seraphs) are changed beyond reason. Tangible Reapers also have dark red blood (as opposed to the glowing blood that angels usually possess). Others, like Death Maidens, are translucent and composed of ethereal streams. Many Reapers show pale, tangible skin, and some (like Anarchs) even have faces, although those appear like eyeless masks with disfigured facial features and a menacing grin. Reapers of angelic origin are quite different from their relatives of the High Heavens. The Horadrim Lorath Nahr was an exception, and he took notes of the Reapers he encountered where no one else could. Information on the Reapers is scarce as most who encountered them perished. The force was primarily led by angels, with undead and other thralls serving under them. The Reapers were a macabre combination of ghastly spirits and baleful constructs.
