Rhombus Square

The pulsating heart of CrossWorlds. Only accessible for advanced players.

**Rhombus Square** is a location in CrossWorlds. It is the capital of Shadoon; a large city of tall glass skyscrapers located on an island off the coast of the Croissant. The main city is only accessible to experienced players who have progressed along the Track of the Ancients to collect the four elements and complete the Trials of the Golden Bugs quest. Until then, it is only possible to visit the tutorial region, Newcomer's Bridge, and the teleportation hub, Cross Central. An aditional pass is also needed to access the entire city.

## Layout

Newcomer's Bridge is a long stretch of buildings with an elevated walkway, located east of the main city. Individual stretches of the bridge are only connected by sections of the Rhombus Dungeon. CrossCentral is a large building containing a teleport hub, from which anywhere in the playground can be accessed. CrossCentral is connected to Newcomer's Bridge via sky rails, a virtual elevated transport system.

The main city has several large, connected areas, and is not accessible until after obtaining the Meteor Shade. Of particular note are a shopping district in the east and the Arena in the west. The Vestorovich Manor is not immediately unlocked, and is only opened during the good ending storyline. Full access to the rest of the city is obtained at the beginning of Chapter 11, once Sergey gives the Full Rhombus Pass to Lea.

## Role in the Plot

### In CrossWorlds

New CrossWorlds players pass through the Newcomer's Bridge areas of Rhombus Square while completing the tutorials located in the Rhombus Dungeon, although it is mentioned that this section is skippable for experienced players. After the tutorials, they travel through CrossCentral to reach Rookie Harbor.

Near the end of the Track of the Ancients, Seekers obtain the Meteor Shade, which grants them access to Rhombus Square proper. This is an entirely optional area of end-game content.

A new region of the Track of the Ancients, Azure Archipelago, is implemented later (during the A New Home DLC). Access to this area is only possible through Rhombus Square.

### In CrossCode

After Lea escapes from the M.S. Solar, Sergey teleports her to Newcomer's Bridge, right after the second stage of the Rhombus Dungeon. Here, she meets Emilie, who challenges her to a race on the last portion of the dungeon. After the dungeon, Lea is confronted by Apollo, who accuses her of cheating due to her overly high level. Joern soon arrives and defuses the situation. Lea and Emilie then continue through CrossCentral to Rookie Harbor.

After obtaining the Meteor Shade, Lea's friends invite her to come explore Rhombus Square with them, but she can choose to skip this and go directly to the Old Hideout.

Near the end of the game, Lea runs into Albert and Ivan having a chat in Rhombus Square. After realizing who Ivan is, Sergey gets in contact with Albert and arranges a meeting. Lea returns to Rhombus Square and visits Ivan in his mansion, where he subjects her to a Turing test. Details of this are given on the Endings page.

In the A New Home DLC, Lea must pass through Rhombus Square to reach the newly unlocked area, Azure Archipelago. After exploring the archipelago, she returns to Rhombus Square for her fourth duel against Apollo, which takes place in the Open PVP Fields.
