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 of our 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. This Monitor was captured by the Gravemind whilst in combat as it glows dimly and its outer casing appears to be damaged.

Biography


As the Monitor of Installation 05, 2401 Penitent Tangent spent many millennia floating amongst the installations various climates and structures, guarding, testing, and watching the ring.

Each Halo, as well as being a giant weapon, is a research facility designed to study the Flood. As a result those Flood specimens left after the Forerunner activated the rings remained on the Installations. At some point after the activation of the Halos, an uncontrollable Flood outbreak occurred, forcing the monitor to search for a Reclaimer. This period in time appears to be known as the 100,000 Years War.

Unfortunately, before he could find one, he was captured and held captive by the Gravemind.



Without the guidance of a Monitor, versed in methods of Flood control, the Sentinel defenses could only fight to a stalemate, eventually creating the Sentinel Wall to physically contain the outbreak within a section of Installation 05, thus becoming the Quarantine Zone.

Apparently, 2401 had been in the clutches of the Gravemind for some time, and was overjoyed when he came upon the sight of the captured Master Chief, believing a Reclaimer could finally activate the facility and contain the Flood outbreak. A short argument with a semi-deceased High Prophet of Regret demonstrated that Penitent Tangent employs a great amount of regulation and protocol when it comes to dealing with the threat of the parasite. Gravemind quickly quieted and pulled them away into the unknown. This Monitor has not been seen since and his whereabouts and status are still unknown.

The 7 Motif
Also of interest is the fact that Penitent Tangent's number (2401) is 7 to the power of 4 whilst Guilty Spark's number (343) is 7 to the power of 3, as the number 7 is used frequently in Bungie games and mythology. Also, 2+4+0+1 = 7. It should be noted that 343 times 2401 equals seven to the seventh power (823,543).

Also, one must note that there are seven unique letters in "Penitent Tangent".

In an earlier Bungie series, namely Marathon, names were often found to be sevens. A numerology grid was used as shown: 0 1 2 3 4 5 6 7 8 9 a b c d e f g h i j  k l m n o p q r s t  u v w x y z

Penitent Tangent is thus P e n i t e n t 5+4+3+8+9+4+3+9=45, 4+5=9 T a n g e n t 9+0+3+6+4+3+9=34, 3+4=7

9+7=16, 1+6=7.

Plus, 3x4x3=36, 3+6=9, 2+4+0+1=7, 9+7=16, 1+6=7.

In the Marathon: Durandal port to Xbox Live Arcade, there is an achievement called, "Hats off to 819." The text is thus, "The secret of 2401 lies within." This may reference 2401 Penitent Tangent. 819 divided by 7 is 117. 2401 divided by 7 is 343.

Backwash
Penitent Tangent also appears in the Multiplayer map 'Backwash', where he hovers around in the air, occasionally talking quietly to himself. He serves no strategic or combat value whatsoever and never ceases movement. Initially, Bungie wanted to use 343 Guilty Spark instead on the map, but testers kept thinking he was a plasma grenade being thrown, so he was immediately changed to Tangent. Nevertheless, the voice remains that of Guilty Spark. They either forgot to change his voice or had no time to do so, or wanted to keep it like that.
