Glyph Batteries, sometimes referred to as Glyph Eggs, were part of the Glyph magic network used by the Sarafan and Hylden in Blood Omen 2. Glyph Batteries were seen throughout Blood Omen 2, they were primarily used as 'conductors' in the Glyph magic network, though the name suggests they may also store a certain amount of Glyph Energy 'charge' (this could also explain their volatile explosive nature).Kain first encountered a Glyph Battery in Chapter 3: The Lower City[BO2]. Like the rest of the Glyph magic network, Glyph Batteries were maintained by the Glyphwrights[BO2].
