2401 Penitent Tangent

"Of all the objects our Lords left behind, there are none so worthless as these Oracles! They know nothing of the Great Journey!"

- The Prophet of Regret

"And you know nothing about containment! You have demonstrated complete disregard for even the most basic protocols!"

- 2401 Penitent Tangent

2401 Penitent Tangent is the Monitor of Installation 05. Although only shown briefly during the encounter with the Flood Gravemind deep in the bowels of Halo, 2401 Penitent Tangent is nearly identical to its brother monitor, 343 Guilty Spark, with the exceptions that its voice is deeper than Guilty Spark's and its light glows red instead of blue, possibly indicating a state of Rampancy. This Monitor was captured by the Gravemind whilst in combat as it is in "defense mode" and glows dimly and its outer casing appears to be damaged.

The only other difference from 343 Guilty Spark apart from his deeper voice and red glow is that the holes on the side of 2401 Penitent Tangent are rectangular instead of round. He is not encountered again after the Master Chief sees him beneath the Library of Installation 05, and he isn't seen when Gravemind occupies High Charity. It is unknown where he went after the first encounter, it is unknown if he is even alive.

Penitent Tangent is slightly younger that Guilty Spark due to that Installation 05 was built after Installation 04.
