Krogan

The Krogan are a species from the Mass Effect universe.

Attributes

Krogan are large, heavily built humanoids of reptilian ancestry. Krogan are strong, durable, and adaptable creatures with life spans measured in centuries. They have numerous redundant organs, and their wounds heal with astonishing speed, fueled by nutrients stored in the humps on their backs.

History

The Krogan homeworld of Tuchanka was home to a wide array of aggressive fauna, requiring the Krogan species to breed aggressively to survive. Against all the predators of Tuchanka, only one Krogan newborn in a thousand could expect to survive to maturity.

The predator threat subsided only after the Krogan developed advanced weapons technology, eventually devastating their planet in nuclear war. The harst post-war ecology continued to keep their population in check until the Salarians transported Krogan off their homeworld so they could fight another species (the Rachni). The Krogan won, but they became a problem themselves when removed from the hostile environment of their homeworld, as their population began to grow rapidly. Krogan began to expand beyond the planets granted to them by the Citadel Council, even invading planets populated by Citadel member races. The Turians used superior technology and strategic intelligence to devastate Krogan armies, but despite massive casualties, the Krogan population continued to grow. To mitigate the Krogan threat, the Salarians created a genetically engineered disease called the genophage to reduce Krogan reproduction to its pre-industrial level, and the Turians unleashed it on the Krogan population. No longer able to replace their staggering losses, the Krogan were finally defeated.

Threat Assessment

While individual krogan are typically strong and incredibly durable, as a political faction the Krogan are of marginal importance in the Mass Effect universe. The Krogan are divided into numerous armed camps that feud with each other, and their reduced reproduction rate is barely sufficient to replace losses.
