The defenders on The Bulwark protecting Tirisfal from the Plaguelands are on constant alert.  But sometimes Scourge will slip past them.$B$BOur success at the Bulwark depends on a one-front battle - we cannot allow an attack from the rear, nor can we allow our defenders' supply line to be cut.$B$BAssist the Bulwark.
