The mercenary axeman is an NPC that attacks a couple of Armadyl Guardians behind McGrubor's Wood during a cutscene in While Guthix Sleeps. The player must help the Guardians and kill the two axemen to proceed. Also fighting alongside the axemen is a mercenary mage, who manages to teleport away when the player attempts to kill him. Afterward, the player talks to the wounded Guardian of Armadyl and is later introduced to Idria.
The axemen slay the followers of Armadyl.
