Thessia

Thessia is the homeworld of the asari. The planet is dotted by loose confederacies of great republican cities – including Serrice and Armali – that function in an overall democracy connected by the asari internet. Many of these cities are home to craft guilds legendary for the quality of their bio-amps.

In Mass Effect: Revelation, David Anderson drowned his sorrows at Chora's Den with a liquor from Thessia called 'elasa'. Edan Had'dah was also fond of dressing in the latest Thessian fashions.

Thessia is a terminus on the Illium-Thessia shipping lane.

Description
The asari homeworld is the core of the largest economy in the Milky Way, due largely to reserves of element zero so vast they affect its price galaxy-wide. Thessia is home to abundant life that has evolved in an eezo-rich environment, leading to a wealth of biotically active species and many more that simply resist eezo's negative effects. Under normal peacetime conditions, travel to the planet is strictly controlled, but even the best efforts of many governments cannot prevent constant smuggling attempts. ALLIANCE ADVISORY: Dust-form element zero can be present in minute amounts in Thessian food and water supplies; however, this has no documented benefits to sapient non-asari species. Non-asari are encouraged to select "visitor" versions of local cuisine, which are kept free of eezo.

Mass Effect 3
Commander Shepard will visit Thessia at some point in Mass Effect 3.

Trivia

 * "Thessia" is adapted from Thessaly. Roman writers such as Ovid and Seneca held that the "witches" of Thessaly had the power to draw down the moon.
