The greatest city of the Asura is a wonder of arcanic architecture. It is a great subdivided cube that floats over the surrounding terrain, impressing all the races with the might of its magic.
— In-game description
Rata Sum (pronounced rahta soom) is the capital city of the asura and is in the form of a giant, floating cube. When the Great Destroyer drove them from their homes in the Depths of Tyria 250 years ago, they arrived at the ruins of some previous civilization, setting up geomystical generators for power within these already fortified confines and establishing the area as their new capital. The aesthetic sensibilities of these ruins are reflected in modern asuran architecture.
Originally a hastily erected outpost protected by ruins, Rata Sum is now a geometrical masterpiece and testament to the asura's unstoppable ability to progress.

- Advanced Metamystics Lab is only accessible during Forging Permission and Hazardous Environment. You can access it by glider or mount, but you will discover that the asura portal doesn't work.
- Although mechanically counting for the Maguuma Explorer, in lore it is part of the Tarnished Coast.
- Polymock arena can be seen by gliding from the top of the city, but here again, you can't use the portal. The area seems finished, but inaccessible. Invisible walls prevent the player from reaching it.
- Internally at ArenaNet, this area was known as "Wetland_Complex."
- 'Rata Sum' is an anagram of 'Mursaat'.
- Two of the possible translations from Latin of "Rata Sum" are "I have calculated" and "I am certain".
- The Polymock Arenas are currently not available for exploration.
- Players will be transported to a Peacemaker jail cell if they attempt to fall to the ground from the sides of the city.
