Adena

Adena is a former Terran Dominion planet, located in the demilitarized zone between the Dominion and Daelaam.

History
Adena was a Terran Dominion mining world, which was able to mine jorium crystals. However, during the conflicts of the 2500s, the world was abandoned. After the End War it was put in the demilitarized zone between the Terran Dominion and Daelaam territory. At some point the zerg arrived on it.

After the Defenders of Man Insurgency, a group of Terran Dominion marines and mercenaries under Captain Hogarth came to Adena to salvage a mining base there for its jorium, hoping to take it for themselves and sell it on the black market. The Daelaam under Admiral Urun watched the terrans, knowing they were lying about their good intentions, but allowed them to land under his watch.

The terrans landed at the outpost and found eighteen jorium crates, but a marine named Elms noticed some zerg creep in the base. Just then the zerg forces there attacked the marines.
