Location: Milky Way / Nimbus Cluster / Mesana System / First planet (Lesuss)
The monastery houses a large population of Asari with active or latent Ardat-Yakshi genes, a disorder that causes the death of anyone who mates with the afflicted Asari. Although some of the colonists exiled themselves voluntarily, many were sent to Lesuss by their families to protect society from their deadly potential.
The monastery emphasizes individual sacrifice for the good of the community. Latent Ardat-Yakshi, as well as active sufferers who show that they can control their condition, may be offered a chance to reintegrate into Asari society after spending sufficient time on Lesuss. Active Ardat-Yakshi whose psychological profiles show capacity for neither empathy nor re-education are confined to the monastery for life, sometimes in prison-like conditions if needed.
Lesuss itself is an unpopular garden world, with characteristics just outside of the comfort zone of its Asari population. Its gravity is a little too high, its diseases a little too virulent, and the soil inhospitable for growing food. Further information is difficult to come by—the Asari government is uncharacteristically silent about Lesuss. Normally, a garden world settled so long ago would be highly populated, but little light pollution can be seen on Lesuss’s night side.
