The Storm Gem is in the Tower of Knowledge, on the way to The Necronomicon (Gamer Guides' route, 6:33). It unlocks the Holy Sword Endu's ultimate attack. Recovering it gives the achievement Raging Tempest — 22.8% of players had it on Nov 2. One player's route to the True Holy Sword Akunra also needs it.
