A star system in the Delphic Expanse where the Xindi tested a prototype of their planet-destroying weapon on a moon in late 2153, watched by Enterprise and the Andorian ship Kumari.
The Calindra system is the setting of the Enterprise episode Proving Ground. The Xindi choose it as the place to try out a scaled-down prototype of the weapon they are building to destroy Earth.
Enterprise tracks the test there with unexpected help from Commander Shran and the Andorian warship Kumari. Posing as traders, the Andorians get close enough to gather scans while Archer watches the prototype blast a moon, though the weapon overloads and the test is only a partial success.
Shran's real orders are to take the prototype for the Andorian Imperial Guard, and he seizes it. Archer sends its arming codes and the device is destroyed, but the Andorians quietly pass their sensor data to Enterprise.
