Keldagrim trapdoor
The Keldagrim trapdoor is a Trapdoor Shortcut and can be found in the north-west of the Grand Exchange. The trapdoor was released on 26 November 2007 along with the Grand Exchange but had no use until the release of Forgiveness of a Chaos Dwarf on 9 September 2009, when it was updated so players could use it to take a free mine cart trip to Keldagrim. This was done to make Keldagrim more accessible. Before the release of the mine cart station many players speculated about what was under the trapdoor. Many players believed that it would be used in a future quest. If you haven't visited Keldagrim, and attempt to use the trapdoor, you will get a message saying "You must visit Keldagrim to use this shortcut". Before the release of the trapdoor, players had to travel through a cave northeast of Rellekka to reach Keldagrim, or use the Mine Cart system. Players can use quick travel methood, that bypass the option to travel or not, by clicking the right mouse button on the trapdoor and click 'Quick-travel'. fi:Hidden trapdoor
