Kalvessan

The Kalvessan or Starwolves are a genetically engineered humanoid race from Thorarinn Gunnarsson's The Starwolves series of novels.

Description
Kalvessan Starwolves appear to be short humanoid creatures with a stocky body, four powerful arms and elvish-like features in their head and face. They are engineered to withstand heavy G turns in space and long trips in space travel. They are bred for space and space combat.

They are very fast and extremely strong, able to lift two tons without a lot of effort. Their bone structure is iron-based giving them a strong skeleton that can take a lot of punishment.

History
Kalvessan were created by an ancient race called the Aldessan of Valtyrs.
