Manila Cathedral

The Manila Metropolitan Cathedral-Basilica (Spanish: Catedral Basílica Metropolitana de Manila), informally known as Manila Cathedral, is a Roman Catholic basilica located in Manila, Philippines, dedicated to the Blessed Virgin Mary as Our Lady of the Immaculate Conception, the Principal Patroness of the Philippines. The cathedral serves as the see of the Archbishop of Manila, the de facto Primate of the Philippines.

Located at Plaza de Roma in the Intramuros district of the City of Manila, the cathedral was originally a parish church owned and governed by the Archdiocese of Mexico in 1571, until it became a separate diocese on 6 February 1579 upon the issuance of the papal bull, Illius Fulti Praesido by Pope Gregory XIII. The cathedral was damaged and destroyed several times since the original structure was built in 1581 while the eighth and current incarnation of the cathedral was finally completed in 1958.

The basilica has merited a papal endorsement from Pope Gregory XIII and three apostolic visits from Pope Paul VI, Pope John Paul II and Pope Francis. On 27 April 1981, Pope Saint John Paul II issued papal bull Quod Ipsum designating the cathedral as a minor basilica by his own Motu Proprio.

It is the headquarters of the Malleus Maleficarum based in the Philippines. Hidden beneath it is a series of tunnels and chambers that house armories, meeting halls and magical circles. These tunnels also connect to the vast network of labyrinthine tunnels and dungeons beneath Intramuros.

Derp-related Activities
It's secrets were first encountered by Josh Fausto, who shares some history with the Malleus Maleficarum. There, they met a certain Priest who maintains the armory of guns used to hunt vampires, witches and demons.

San Agustin Siege
A few months later, during the San Agustin Siege, the Malleus Maleficarum moved to act against the ancient Leviticus conspiracy that resurfaced nearby. It just so happened that the Derps had also decided to infiltrate the catacombs in order to save their female friend from the cult. The priest gave them information on the underground tunnel network and brought a detachment of gunmen and warriors to take an alternate path. Later, they cleaned up the remaining Leviticus members after the Derps beheaded the Leviticus cult.

El ajuste de cuentas de Dos Demonios
6 months after the siege, Derpman accepted the aid of a Malleus member in the binding of the demon Jom, who resurfaced as Mr. Moon begun hunting them down. After much discussion and pleading, the plan was changed so that the Derps would attempt to draw out both demons here, with the priests exorcising them both at once. The plan worked, but Mr. Moon's Merceneries soon stormed the plaza after emptying the streets and removing all witnesses. The Plaza de Roma was the site of a gunfight that ended with the Derps forcing the Mercenaries to retreat.

The NBI covered up this incident as a drug deal gone awry, with them stepping in to arrest the stragglers.
