Asari

Asari are strange blue-skinned beings that are a member of the Tri-Council along with the Salarians and the Turians. They hail from the planet Thessia, and were certain that the Reapers did not exist, until they existed and killed them all. Now the Asari live only as a border race, clinging onto what little their planet can offer them, after their cities were razed and their food supplies devastated, they rely entirely on the GTS for support. However, their race prospered in the past, so there is no telling where evolution will take them next. They were able to retain their massive flagship, the Destiny Ascension, which aided massively in both the Reaper War and the following relief effort for the Asari.

An Asari was rumoured to be aboard the Normandy, which apparently carries Asari charity leaflets across the Galaxy asking for aid for their race. So far, no one has stepped forward.
