History of Glyphkeepers

The Glyphkeepers are major Scorn Chieftains in the Exhibition encounter of Vow of the Disciple, and they also appear in the Acquisition and Dominion encounters. Each one shows three glyph symbols when slain, and the fireteam must kill both Glyphkeepers within a few seconds of each other to reveal the next glyphs. The Glyph To Glyph challenge asks for each pair to be killed within 5 seconds of each other.
