The Land of Tombs and Krypton, abbreviated as LOTAK, is Dirk Strider's planet in the Post-Scratch Medium, and is one of the main four planets of their session. The planet shares themes with the rest of the sessions' planets of burial places and noble gases, representative of the dead end/inert nature of their session.
The kids use what appear to be gas masks in order to breathe in the thick krypton gas, when they descend through the towers and levels below. Krypton gas sinks, so the masks are seemingly not required at the elevation of Dirk's house or the tallest rooftops, where the gas is thinnest.
The atmosphere of the planet is green and orange, with large arcs of what could either be electricity or plasma scattered around the surface.
The planet suffered serious damage in its collision with LOMAX in the battle between the Condesce and Aranea Serket, but it has been reverted to its former state after John's retcon powers undid the battle. It was subsequently all but destroyed in the aftermath of Collide.
- While krypton is inert and therefore non-toxic, breathing air with a high krypton content can cause symptoms similar to nitrogen narcosis due to its high density. In addition, if there is enough krypton in the atmosphere to displace oxygen, it can act as an asphyxiant. Either situation would explain the use of gas masks.
- The tombs resemble the temples of the Khmer Empire (stretched to exaggerated heights, much like the skyscrapers of Prospit, Derse and Alternia's green moon and the homes of SBURB/SGRUB players). This is probably a reference to Lara Croft: Tomb Raider, in which Lara Croft retrieves half of an ancient, magical artifact from a Cambodian tomb.
