Gromar is a rocky terrestrial world with a trace atmosphere of krypton and xenon. The frozen surface is mainly composed of copper with deposits of calcium.
Prior to the Alliance's expansion into the Voyage Cluster, Gromar hosted one half of a turian interferometric telescope array. Connected with similar telescope in the Attican Beta cluster by an expensive chain of FTL comm buoys, the two functioned as a single virtual "lens" with an effective aperture equal to the thousands of light years between them. The turians used this to chart the Terminus Systems with great accuracy.
- Note: This planet can be surveyed for a League of One medallion.
