A Study on Aztec Culture Pertaining to RPC-042


Several theories and speculations have been made concerning the origins of RPC-042. Dr. Matte Chrome made a formulated hypothesis that RPC-042 may have originated in Latin America. Particularly in the Mesoamerican period due to its 'screeches' similar to that of the Aztec death whistle.

Archaeological expeditions commenced on March 28th, 2003, for four months. During these expeditions, several discoveries were made that substantiated the possibility of RPC-042's Aztec origin hypothesis. Funding was approved by the Office of Analysis and Science (OAS).

Below is a report of abstract findings based on collected and interpreted evidence.

Mesoamerican Aztec and the Sacrificial Persecution

Fig. 1-0: Aztec sacrifices during the post-classic period.

During the post-classic period (900-1521 CE), the Aztec civilization grew and expanded its influence and territory within Central America.

While there are many factors that lead to the civilization's rise, factors such as its theocratic society and sociopolitical organization may have been a large contribution to its dominance at the time. Due to their ascendance as a civilization, the Tepanec saw the Aztecs as a neighboring rival. Tensions between the Tepanecs and Aztecs caused hostility and conflict.

Sometime in the 1420s when the Aztecs were at war with the Tepanec, Aztec sacrificial rituals increased for unspecified reasons. While some factors contribute to the increase of sacrifices, such as captured prisoners of war, there may perhaps be more of possible explanations:

  • With relations with the Tepanec strained, many within the Aztec royal family feared a coup d'etat by defectors and outside spies.
  • The expansion and integration of territories once owned by rival civilizations caused the Aztecs' issues, namely overpopulation and high birth rates.

Another possible explanation is an abrupt change in the Aztec way of worship. As a religious society, the Aztecs may have interpreted the war with the Tepanec due to insufficient worship or neglect of religious duties, increasing their appeasing rituals to ensure their civilization's prosperity through the conflict.

Paranatural Methodology in Conflict

By 1428, the Tepanec civilization was close to collapsing in the war against the Aztecs and their allies. Many desperate measures were enacted. However, it appeared that the Tepanec leadership opposed resorting to these measures for supernatural reasons. Despite the opposition, these measures were carried out regardless.

However, according to various potteries and texts left by the Tepanec, at least one group continued to attempt to use a cultural equivalent to forbidden or black magic, to no apparent success. The rate of performance of rituals grew as the Aztec drew close to the Tepanec capital of Azcapotzalco, and abruptly ceased before its fall."

It is uncertain if these attempts were successful, but there's substantial evidence to suggest that they performed as the Tepanec capital of Azcapotzalco almost came under control by the Aztecs.

At an excavation site, designated as Sector-042/5, archeologists uncovered an underground area that contained wall carvings that depict a Tepanec priest performing rituals on a corpse with visible body modifications.1

A black circle above the body was spotted by Dr. Francis, suggesting that the ritual was performed during a solar eclipse. The last wall carvings depict the individual rising from the table and attacking the Tepanec priests. Further adding that a group of humanoids were attacking the Tepanecs, described as tall demons with their skeletal areas exposed.

It is believed that Azcapotzalco fell before the Aztecs reached it but fled the city as their rituals proliferated. Most recent records of the Tepanec make extensive reference to a previously-unseen type of demonic entity nicknamed the 'Night Terror.'

We don't know much about this specific ritual or what they're trying to cast on the person. Given what we know, the practice must've given those affected the ability to hear with great distance and stronger muscles and bones.

This is all in theory, but we have encountered something like this in the past with other registered anomalies. It's certainly not impossible to say that this spell does cast the properties mentioned above.

Aztec Civilization Counteracting the Night Terrors

Following the collapse of Azcapotzalco in late 1428, the Aztecs swiftly retreated, leaving the city abandoned. It appears that, unable to effectively combat the Night Terrors, they were forced to leave conquered areas in favor of their own, safer territory.

According to several texts and rock carvings left by the Aztecs and Tepanecs, the initial Night Terror that was spawned by the Tepanec had multiplied by itself after the Aztecs initially had some success in hunting and destroying the spawned Night Terror. It resulted in the spawning of more Night Terrors and the loss of many Aztec war parties. It is unclear how the Aztecs successfully developed a method to neutralize a Night Terror, let alone how many Night Terrors were spawned due to their neutralization methods.

Interestingly, the Aztecs increased their en masse sacrificial rituals to have the gods spare them from the Night Terrors. However, it is clear that this method did not work and only pushed to weaken the Aztec civilization.

However, by 1429, the Aztecs civilization and neighbors created a coalition of warriors and priests to fend off the growing Night Terror species.

In the same year, they somehow developed a ritual that would specifically contain Night Terrors that would not result in the neutralization and eventual spawning. Again, information and evidence about their sources of methodology remain limited. The Aztec Death Whistles appeared to have been developed as a counter against the Night Terrors due to their loud audible, quickly subduing a spawned entity, similar to that of modern procedure in using a flashbang.

However, in several designates sites, there was an abundance of evidence of neutralized Night Terrors, one discovered in a mummification and burial method, as seen in Fig. 1-2.

Spanish Papers

At the early hours of Thursday, one of the excavation teams uncovered what appears to be a former Spanish Outpost at Sector-042/007.

Outpost seems to have been abandoned a long time ago, with the jungle elements taking over. We searched around with nothing uncovered so far, but we found a sealed underground area with numerous Spanish artifacts and documents within a few hours.

A few remains of the former inhabitants were found nearby, though we speculate that they perished from unknown causes.

Below are Spanish documents recovered from the Spanish outpost.
