A planet in the Kite's Nest, a formally prosperous colony of the Batarian Hegemony.
To quote rightful ruler Mano'har-Mohak Vorkhet Jagdish-Dasharathak IX:
"You see, Greklon had -- and dare I say it, still has -- the potential to be a galactic trading hub to rival Illium. Perfectly situated on relay routes between Alliance/Council, Batarian and Terminus space, it was left to metaphorically and physically rot by a Hegemony too lazy to see that war with Humanity got us nothing."
Native fauna includes the Hrokfish, which can reach impressive sizes, and the rothkith, a type of reptilian scavenger with brightly coloured frills. Rothkith Hunts are common events on Greklon.
Mano'har-Mohak Vorkhet Jagdish-Dasharathak IX is in exile. The current ruler is his younger brother, Mano'har-Mohak Vorkhet Jagdish-Dasharathak X, and an abolitionist. For the surviving, mostly slave caste populace of Greklon, he was a much more palatable choice, especially as the younger Mano'har stayed and fought the Reapers alongside the slaves, while the elder spent the Reaper War in relative comfort on the Citadel.
