Lystheni

The Lystheni are an offshoot of the Salarians. The races has always been reclusive, keeping to its worlds in the Terminus Systems, far away from Council control. When the final assault on the Reapers occurred, the Lystheni wanted no part in it.

History & Culture
The Lystheni originated upon the southernmost continent of Sur'Kesh and were always a more hardy and driven peoples. Their conflicts in the past with other Salarians carried over into the space age.

As time went by the division between the Salarians and the Lystheni only grew, as cultural differences discouraged interbreeding. The Lystheni for example fertilize 50% of their eggs, resulting in an equal population of females, a practice that other Salarian cultures find barbaric.

Eventually war erupted between the Salarians and the Lystheni, the Lystheni modified their offspring to produce a more resilient peoples using DNA modeled from Krogan genetics. However, the Lystheni did not succeed in their war, and they retreated into the Terminus Systems.

When the mass relays were destroyed they hardly noticed, keeping to their sector, thankful that nobody could intrude upon them any longer. The Parnack Regime arrived in their sector though, war erupted between the two forces, as both had strong fleets the war lasted decades.

Ultimately the Yahg succeeded, they assimilated the technology and peoples of the Lystheni, this race has likely the highest population of any race in the Parnack Regime, providing diverse roles in the society.

Biology
Biologically the Lystheni are hardly any different from mainstream Salarians, they live much longer lives, and are considerably stronger. Their biological differences are the result of separation and genetic modification.

Natural separation from the mainstream Salarians resulted in hardier physiques because of the sub-arctic waters, more durable eggs, with shorter gestation time. Their skin is thicker, and they are more capable of accumulating weight.

The genetic modifications are not omnipresent in the peoples, but the modifications have resulted in greater genetic diversity amongst the Lystheni. The revised genetics were modeled after Krogan genetic material, this resulted in increased strength, longer lifespans, and an increase in aggression. There are negative side effects, there is a high rate of arthritis and lung disease amongst the Lystheni.

No actual Krogan DNA is present in the Lystheni, the Salarian DNA was modified using Krogan genetic logic. It was not a perfect process, and on occasion eggs are born with hard shells like Krogan eggs. The result of a hard-shelled egg is a child that dehydrates, and a mother who will no longer be able to have children.
