Infinite Sacrifice
From Halopedia, the Halo Wiki
Infinite Sacrifice was a Covenant ship. It is the Prophet of Regret's personal ship, most likely an Assault Carrier.[1] Regret was present on board Infinite Sacrifice during the Battle of Charybdis IX.
This ship may also be the Assault Carrier he used during the Battle of Earth and the Battle of Installation 05.[citation needed]
It is unknown if this Assault Carrier was destroyed in the Great Schism, or if it was captured by the Flood after the Prophet's demise, or even captured and used by the Sangheilian Armed Forces after their secession from the Covenant. If this vessel is in fact Regret's Carrier, it can be seen in the levels Outskirts and Metropolis, and in some parts of Delta Halo.
