Spawn

This starting area, or spawn is where players start their RetroMC experience.
A few buildings are here to help most players out.
Players are invincible in here and the surrounding town, so fall damage, drowning and lava damage are nothing to worry about.

Spawn island

Intro

When a player first joins the server or uses /warp intro, they'll be greeted with signs telling them to register a password using /register <password>.
The area itself displays all the rules and information about the server.
Most of the frequently asked questions are answered here and several signs are placed as a reminder to check the rules.

Spawn

The spawn island area contains a couple buildings, some of which have purposes, others empty.
Players who join without authenticating via BetaEvolutions or similar, will be teleported here to enter a password, and will then be teleported to the previous location they were at.
/spawn can obviously be used to get here.

Server Shop

Accessed by /warp shop, this establishment allows players to buy/sell items via money.
Items range from basic materials such as wood, wool, and cobblestone, to valuables such as sponges, and diamonds.
Usually better prices can be found elsewhere in Spawn Town, most notably at the Moon and Mall warps.
The market guide goes more in-depth regarding this.

Maccas

A fast-food restaurant managed by JohnyMuffin where you can buy food.
(FYI: Not an actual food shop in RMC)

Nether Portal

A Nether portal with some info about the Nether and lava surrounding it.

Holiday Shop

This building allows players to buy items specific to a holiday, usually Christmas and Halloween.
It's locked in-between holidays, so peeking is discouraged.

Spawn Town

The area just outside of the spawn island. Citizen and above can build in this town, wherein HP loss is of no concern.

Mall

A centralised location for shopkeepers and customers.
From 23rd May 2019 till Sep 2nd 2024, the initial iteration of the mall was home to a bunch of shops, albeit a bunch of them were inactive.
In the months leading up to its closure, the mall caused clients to lag considerably, due to the amount of signs, and among other factors, shopowners were notified that the mall was going to be closed on 1st Sep 2024.
Inactive stalls were purged on that date, and any items that were stored in chests were moved to a secret location.
