The Galgs are a frog-like amphibious xenos species who often serve as mercenaries for the Tau Empire. Members of the Galg race are covered in green scales and appear to most humans as large, humanoid frogs. The Tau Empire normally maintains a small number of Galg mercenaries within their ranks but Galgs can be found in the employ of many different factions across the galaxy as long as the price is right. As with most alien species, the Galgs hate Mankind, even when humans serve as their employers, because of the Imperium's intolerance for all intelligent alien races.
