Gamemode 4D/Landings
Landings is the first dimension players spawn in when they first join Gamemode 4D. The main purpose of this dimension is to feature as a tutorial world introducing newcomers to the inter-dimensional travel system, providing a book containing the Mysterious Note. It also serves well to prevent griefers from joining the server and destroying the main dimensions.
Details
Players spawn with a book directed towards "Audrey" from an unknown author. The book describes a unique item capable of inter dimensional travel: The Mandala. On the last page, there is an cryptic crafting recipe for the Mandala.
Players are randomly spread throughout this dimension when they first join the server. Due to this, animals and resources are plentiful. However, there is a bedrock level at Y=40, so it is not possible to get any ores except for coal.
Once crating the Mandala and using it, the player will be teleported to the Overworld. There is no way of getting back to Landings after teleporting to the Overworld.
