Ward Gates were devices used by the Sarafan to control the movement of Vampires . Kain encountered Ward Gates throughout Blood Omen 2 . Kain first encountered a Ward Gate in Umah 's tutorial in Chapter 1 : the Slums, where Umah described how active gates would burn a Vampire "as by fire", she also commented that touching a gate would sound an alarm to call Sarafan guards. Shortly afterward, attempting to cross a bridge into the Lower City, Umah and Kain were separated when a Glyph Guard was alerted to Umah's presence and turned on the nearby Ward Gate.
