Acolyte is a Grimoire card from the original Destiny (Destiny 1), found under Enemies → Hive. Grimoire cards held most of the game's lore and were read on Bungie.net and in the companion app, not in the game itself.
Card text
It would be a mistake to view the Hive's Acolytes as foot soldiers, because the Hive is not merely an army, it is a dark force rising. It is belief and horror, and its Acolytes are its instruments, hungry to commit the atrocities that will drive their own ascension.
Grimoire text written by Bungie, shown as it appears in the Destiny 1 game files.
