Solemn Penance

The Solemn Penance was the flagship of the Prophet of Regret, which he used to lead his failed attack on Earth during the Human-Covenant War. After being smashed out of orbit by Johnny and his gang, Regret initiated a slipspace jump inside the city of New Mombasa, severely damaging the city and unintentionally dragging the UNSC In Amber Clad in tow. This is how both the Covenant and the Humans found Installation 05.

The Solemn Penance held position above the surface of the ring whilst the Prophet went down to the surface to conduct his 'sermon'. He was killed by Johnny whilse performing some pointless ritual in a completely pointless temple for no reason, and was assimilated into the Gravemind as punishment for his bitter failure. After this, the Solemn Penance joined Truth's Fleet after the Fall of High Charity and fled to Earth, and after escaping to the Ark it was destroyed by Shitmaster's Fleet after being impacted by the Shit Cannon 30,000.
