13 Tribulations

13 Tribulations is the prophicized major antagonistic factions appeared in LOTM: Witnesses of Sleepy Hollow, though it was canoncially 12 until the future Micheal Langdon's interference and becoming the fifth disaster. In the seven-year-war of the Team Witnesses, these villains are the major threats and will be confronted in proper orders.

Note: With the only exception of the future Michael Langdon, there are 12 Tribulations recorded on the Grand Grimoire. They are MOSTLY single individuals (expect the Four Horsemen which four villains combined into one disaster). No other individuals (e.g. Vanifer) or factions (e.g. the Hessians) related to them could be listed here.
