Portals and You
The Multiverse is big. REEEEALLY big. You just won't believe how vastly, hugely, mindbogglingly big it is.
Here follows a bit of basic information about the ways to visit new planets, and what we know about the ones we've discovered.
Most portals cost credits to use (except Earth, which is free to visit). Dibbler's Discount House O' Portals on Spawn Ranch has the cheapest portals around, but he'll charge you each time you use one. If you build a portal out of the correct block and light it with a flint & steel, it will charge you much more... but only once for each planet.
*Malfunctioning Eddie's is temporarily closed; the mgt regrets any inconvenience this may cause.
There's a junk TARDIS at Malfunctioning Eddie's, on Spawn Ranch; anyone can use it (management is not responsible for death, dismemberment, or marooning). TARDIS seeds are for sale on Spawn Ranch; place it on the ground (IMPORTANT: you should do this on your own claim, as this will become your TARDIS's home location) and r-click it with your TARDIS key. Traveling in a TARDIS does not cost credits, but does consume Artron energy.
IMPORTANT NOTE: unclaimed land which is not modified for over 37 days will be regenerated and all modifications will be lost.
Use /lands to begin claiming; everyone gets one free land on joining the server.
PaperMC Vanilla (flat) 1.17.2
Portal block: Bedrock
Where it all begins. There are some shops, an Ender chest, and access to the server's travel hub, known as the portal church. You cannot claim land on Spawn Ranch without special permission. Currently under construction, but most shop NPCs are in place.
PaperMC Vanilla 1.17.2 (live)
Portal block: Cobblestone
This is the starter planet; come here to collect resources, stake a claim, and make enough credits to travel somewhere decent. No leveled or special mobs spawn here.
AlmostFlatLandsReloaded 1.15.2 (overworld)
Portal block: Slime Block
Endlessly sprawling flat land, full of slime and the occasional tree. Adventurers make great targets for the lightning storms you'll almost certainly encounter; don't get caught out in the open!
CityWorld 1.15.2 (overworld)
Portal block: Purpur Pillar
Welcome to the big bad city, Country Mouse! Cybermen abound, acid rainstorms befoul everything, and breaking bookshelves is probably a bad idea. Stay sharp, dig deep, and try not to get upgraded!
Underdark 1.7.2 (nether)
Portal block: Nether Bricks
From the original (abandoned) project page: "...loosely based on D&D's underdark, the home of the Drow. The landscapes generated are filled with lava lakes, bridges, tunnels, and huge stalactites which form the ceiling." Beware the Hungering Darkness.
CityWorld 1.13.2 (overworld)
Portal block: Red Nether Bricks
The entire planet has been declared an "anarchist jurisdiction." Downtown is on fire, the villagers are (un)dead, dogs and cats are living together, the oceans have turned to lava... mass hysteria.
