A key is an item found in the Gnome Village Dungeon, which is very difficult to distinguish from A key (Waterfall Dungeon) . It can be found in a crate in the storeroom to the north east of the dungeon entrance. It opens the door to the cell in which Golrie is contained, found north west of the dungeon entrance. This makes it easy to pick up the key when needed and so there is little advantage in keeping it in the bank. Upon finding it, a player will receive the message "You found a large key". It cannot be stored on a Steel key ring.
Note that if a player has a low combat level, they will likely receive damage from the surrounding monsters while searching the crates for the key.
The key is first used in the Waterfall Quest, and again used in Roving Elves. The key is needed to unlock the door where the gnome named Golrie is hiding from Hobgoblins that have invaded the dungeon. Once the door is unlocked, Golrie will give the player Glarial's pebble, which is required to enter Glarial's Tomb near Baxtorian Falls. Players can repeat this after the quest if Glarial's pebble is needed again. It is recommended to keep this pebble in the bank, or instead Glarial's amulet once received, in order to avoid the need to speak to Golrie again at a later date, since the amulet is required to enter the Waterfall Dungeon and used again in Roving Elves.
The key is also needed in The Path of Glouphrie. You need to access the room that Golrie was hiding in during the Waterfall Quest to acquire extra coloured shapes.
After Roving Elves, Golrie has traded places with the hobgoblins. He is no longer located behind a locked door. As such, a player should no longer need the key if they wish to retrieve Glarial's pebble.
