Trivia

• You have a separate spawn point in each dimension, so it is advisable to bring a key of purity.
• Tartarus and Kronos are not my original idea.
• A geiger counter is a real life tool used for measuring radiation levels.
• You can use NPC house banners to move NPCs through dimensions.
• The Voidlands are a reference to the End from Minecraft.
• Despite being called the ichor key, Tartarus' teleportation item is not crafted from Ichor.
• Feel free to add dimensions, and pages and links for the existing ones (Overworld and Underworld are already existent).
