Old Man Garry

 is an NPC that hosts events in the Dwarven Mines. When there are 20 seconds before the next event starts, a message appears in chat saying what the event is (clicking the message will warp the player to Old Man Garry). Upon an event starting, you can warp directly to where it is happening, by clicking on Old Man Garry and selecting the dye (it will turn green when you can warp).
