Battle of Boreth

The 'Battle of Boreth was a brief side conflict during Klingon Civil War.

Pre-Battle
Prior to the battle, a brave captain, his team, J'Ula, Adet'pa and Martok, with the aid of Tenavik and the monks of Boreth, travelled to Gre'thor to recover the soul of L'Rell. (Leap of Faith)

Upon finding L'Rell in Gre'thor, the team fought their way back to the Barge of the Dead and returned to the Monastery of Boreth, whereupon L'Rell's soul returned to her body.

Upon her resurrection, the captain's ship reported that Fek'Ihri ships were arriving over Boreth, prompting them and Martok to return to their ships, while Tenavik took Adet'pa, J'Ula and L'Rell elsewhere.

Battle of Boreth
Over Boreth, four Fek'Ihri portals opened, deploying a fleet of Fek'Ihri ships.

Once the portals were closed, a large portal opened, and a Fe'rang Dreadnought arrived. At the same time, a task force of ships loyal to J'mpok arrived to assist - calling a temporary truce to defend the neutral, holy world.

Conclusion
Following the destruction of the dreadnought, the forces loyal to J'mpok returned to their space, while L'Rell handed command of her century and a half old flagship, the I.K.S. K't'inga, to J'Ula, who lost her ship, the I.K.S. Lukara, over Boreth just before the mission into Gre'thor.
