Korriban

Korriban is an incredibly friendly planet — JK it's the most fricking hellishly evil planet you'll ever encounter.

History
Until about 2 ABY.

In 2 ABY, a Mandalorian by the name of Opp Timas Prime and a Sun Guard visited the planet and stole a Sith artifact: a rod. They were soon chased to their ship by four angry Terentateks meant to guard the artifact, and after that encountered Anzati who fought the duo after Opp Timas shot one. They managed to kill all their targets and flee offworld.
