Ixth. The lost planet.

Scientists have long debated the existence of Ixth. Some believe it was once a thriving paradise, but an expedition through a mysterious passageway revealed the truth. Ixth was never a paradise, it was always a prison.

When the Lazax Empire was just spreading its wings, it began a bloody war with the mercenaries known as the mahact. The Mahacts were pushed back from planet to planet, until finally only the Ixth remained.

At the end of their desperate attempt to end the war, the Laxax isolated the Mahacts and their home planet from the rest of the galaxy. After millennia, however, the secret of Ixth's existence - and its exact location - reached the ears of easily influenced entities.

As echoes of the past sweep across the galaxy and the prophecy of the Ixth crumbles to ashes, a new flame burns from the still-glowing embers.

The Prophecy of Kings.

Just an add-on, the Twilight Imperium Board Game 4th Edition base game is also required to play it.
