Wizard 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
The Wizard is the scalpel with which the Hive vivisect the universe. A nightmare of rag and bone, the Wizard conceals herself within darkness and fire, dissecting and experimenting on anything that falls into her clutches.
