When you are looking to make a Town, consider the terrain and environment you want to build in. Once you place a Town, you cannot move it without deleting your Town and claiming a new one elsewhere. Spend some time exploring the map and find an area that can meet your development goals and has biomes you like. Building your Town near other Towns makes trade easier, and allows you to interact with more players, but may increase your risk of invasion and war.
Towns are claimed on a per-chunk basis, use F3 + G to see chunk borders.
/t new [name] -- Claim a new Town in the chunk you're standing in, making it the "home block"
/t claim -- Claims the chunk you're standing in, if adjacent to one your Town already owns.
/t unclaim -- Unclaim the chunk you are standing in.
/t claim outpost - Claim an outpost, a chunk that can be separate from your main Town. Use this to exert control over strategic resources, you have limited outposts available to you.
/t invite [player] -- Invite a player to become a resident in your town
/t deposit [amount] -- Deposit money into the Town bank.
/t withdraw [amount] -- Withdraw money from the Town bank
/t buy bonus -- Buy bonus chunks to claim additional land. You can buy (functionally) as many bonus chunks as you'd like, but their cost increases exponentially as you buy more.
/t trust, /t trusttown -- Trusts an individual (or entire Town) to your Town. This grants them additional permissions, for example, Trusted individuals have block place and break permissions, container access, switch access, etc. in all Town chunks that are not privately owned.
After claiming a chunk, Town officials have a selection of plot types they can set a given plot to, for additional control. Plots can be put up for sale to allow residents or even foreigners to purchase and develop that plot of land. Some plot types are designed to permit the construction of publicly-accessible docks for visitors to your Town or temporary moorings for traders. Below are some details for each plot type:
Default - The standard plot type, Residents do not have access by default. Can be put up for sale by the Mayor for Residents to purchase.
Port - A plot type that permits any non-Outlaw/Enemy to switch (interact with doors, chests, etc.) which also permits crafts to move in and out of these chunks. These can be used to make protected public docks or roadways.
Shop, Inn, Bank - Plot types that allow you to create properties with different tax rates compared to other plot types.
Arena - A plot type with PVP enabled, even in non-PVP Towns. Useful for having training grounds or colosseums.
Farm - A plot that lets all residents break crops within it, a useful public amenity.
Embassy - A plot that can be bought by anyone, even non-Residents. Useful for having foreign embassies or foreign-owned shops.
Jail - A plot that can be used to jail Residents and Outlaws that break your Town's rules.
