During the government failures of the Intelligence Wars several raiding groups emerged. This had a lasting affect on ship and space station layouts. Before, ships were designed with very efficient and straight forward layouts. However to deter boarding parties many ships and space stations became increasingly maze-like. Ships of the same class would even have different layouts from each other. This made knowledge of ship interiors very valuable to the right people. Often times members of a ship or station would only have access to partial maps. Complete maps were closely guarded secrets.

For part of the General Galactic Rule ships started to streamline their layouts again. This was one of the ways you could tell different eras of ships apart. Some stations in particular became historical sites noted for their interesting and archaic layouts. Complete maps of historic ships and stations became more widely available as boarding became less common under the General Galactic rule.

Tubers often required additional infrastructure for their Tube Tombs to navigate through. While some smaller or older ships would have the Tube Tombs navigate through the same halls as other crew, the collateral damage this caused led to them having their own dedicated routes. These extra tubes is where they got their name from.

After the Fall of the General Galactic however the galaxy plunged back into smaller groups. Raiding and boarding parties became more popular again. This time though Magic Reintroduction drastically changed how ships could be designed. Ships had intricate layouts that were sometimes magically trapped or could even warp their layouts over time. It was common for ships to be bigger on the inside, sometimes in uneven ways. Navigation inside a ship could become complex enough to require specialized Craftographers, in particular on large space stations or generational ships.
