Captain Milo Rovin is a prominent captain of the Varrock guard. He takes his job very seriously, questioning players for entering restricted areas. Players can also choose to tell him about the castle's ale delivery, in which he will direct it to the kitchen staff.
The captain can be found on the second floor of the north-west tower of the castle, at the top of a spiral staircase. But other than quests and dialogue, he has no use.
During Defender of Varrock, his scout Hartwin has reported seeing some zombies in the Graveyard of Shadows in the Wilderness. Players are told to investigate this and the quest is started.
During River of Blood, players must gather a blisterwood polearm, blisterwood sickles, and some steel equipment for him and his men, and work to fend off some vyrewatch.
During Dimension of Disaster: Defender of Varrock he prohibits living humans from climbing up the stairs to the 1st floor[UK]2nd floor[US] of the castle. To fool him, a full zombie outfit must be worn.
