The Order is the rival of the Historics Assembly. While the Assembly is a public institution under the leadership of Archmage Rezard Valis, the Archmage secretly supports the Order. This is because the Assembly is full of self-righteous and arrogant historians, while the Order employs mercenaries who usually only care about money (And thus the political problems of the Assembly are eliminated and only hard evidence is delivered).
Though the infighting of the Historics Assembly is not to be found in the Order, there may still be problems with mercenaries who do not hold up their end of the bargain, either by returning false evidence or abandoning the contract entirely. However, such mercenaries are always caught by Asmodan, who possesses the Knowledge Rune, one of the 16 Runes of Power. The Rune grants Asmodan great knowledge of the past and present, as well as the avatars of Huginn and Muninn, magic ravens who can return any request for knowledge and also serve as Asmodan's steeds. Using the Rune, Asmodan can track any mercenary who works for the Order and stay up-to-date on their activities.
