Personal Realm Key

Quickstart

1. Craft the Personal Realm Key and hold it in your hand.
2. Right-click to teleport into your own private realm — a small grass island generates automatically on your first visit.
3. Explore the island: there's one random tree to chop and a fully-grown crop field to harvest.
4. Right-click the key again while inside to return to exactly where you came from.
5. To share your realm: Sneak + right-click the Personal Realm Key to receive an unbound Guest Realm Key, then hold it and type /bind to link it to your realm. Give the bound key to a friend.

Overview

Personal Realm Key gives every player their own private pocket dimension that behaves like the Overworld. Your return location is saved directly on the key, so logging out or restarting inside the realm is safe — you'll always come back to the right spot. No one else can enter your realm unless you hand them a bound Guest Realm Key.

What It Adds

How To Use

Personal Realm Key

• Enter your realm: Hold the key and right-click. Your current position, dimension, and facing are saved onto the key, then you are teleported in.
• Leave your realm: While inside, right-click the key to return to the exact position you came from.
• Create a Guest Key: While outside your realm, Sneak + right-click to generate an unbound Guest Realm Key into your inventory (or dropped nearby if full).
• There is a short cooldown (~2 seconds) between uses.

Binding a Guest Key

1. Hold the unbound Guest Realm Key in your main hand.
2. Type /bind.
3. The key is now bound to your Personal Realm. Its tooltip will update to show your name.
4. Give the bound key to whoever you want to invite.

Guest Realm Key

• Visit: Any player holding a bound Guest Realm Key can right-click it to teleport into the realm owner's island.
• Leave: Right-click the Guest Key again while inside to return to wherever you were before entering.
• Each visitor's return location is saved on the key independently.
• The key's tooltip shows which player's realm it leads to. An unbound key shows an error and does nothing.

Revoking a Guest Key

Type /remove <playername> (you must be the realm owner) while that player is online. Any Guest Realm Keys bound to your realm that are in their inventory are immediately destroyed. Only online players can be targeted.

Abilities And Mechanics

Your Personal Realm

On your first visit a unique 48 × 48 block island (3 × 3 chunks = 9 chunks total) is generated:

• A flat grass surface over layers of dirt — open sky above, no ceiling.
• One randomly placed tree — oak, birch, spruce, jungle, acacia, or dark oak.
• One small crop field (7 × 7 farmland) — fully-grown wheat, carrots, potatoes, or beetroots, with a water source block at the centre to keep farmland irrigated.

The island generates only once. All changes you make persist across visits.

Overworld-Like Behaviour

The realm has a full day/night cycle and dynamic weather, just like the Overworld. Mobs can spawn normally.

Return Data Saved on the Key

Your return coordinates (dimension, X, Y, Z, and facing direction) are written directly onto the item the moment you activate it. This means:

• Logging out or a server restart while inside your realm is safe — the key still knows exactly where to send you back.
• Guest keys also save each visitor's individual return location the same way.
• If you use a different key to try to leave the realm (not the one you entered with), it will have no return data and you will receive an error message. Always keep the key you entered with.

Island Isolation

Each player's island is placed at a unique coordinate offset inside the shared realm dimension, derived from their player ID. In normal play it is effectively impossible to stumble onto another player's island without a guest key.

Crafting And Obtaining

Personal Realm Key:

Guest Realm Key — can also be crafted directly, or generated by Sneak + right-clicking a Personal Realm Key. Either way, the crafted version starts unbound and must be bound with /bind:

Progression And Strategy

• Early game: Your realm's crop field is fully grown on arrival — harvest it immediately for a quick food boost. The tree provides early wood in complete safety.
• Safe base: Build a private shelter or storage room that no other player can access without a guest key you explicitly give them.
• Safe logout: Teleport into your realm before logging off on a dangerous server. The return point is stored on the key item itself, so logging out or a server restart won't lose your return location.
• Sharing your realm: Sneak + right-click your Personal Realm Key to produce an unbound Guest Key, hold it, and type /bind to link it to your realm. Hand it to trusted friends.
• Revoking access: Use /remove <playername> to instantly destroy any of your guest keys that an online player is carrying.
• Keep your key safe: The return data lives on the specific key you used to enter. Losing that key while inside the realm means you cannot return to your original location through that key.
