Marcus the Blasphemer

Scholar and prophet (883-930). Believed to be born in Tronis, Vesland, Marcus was adopted by the Thoth priesthood around 891 after predicting that the Ontainians would soon conquer Kangrisorn. He was considered particularly gifted, and when his prediction came through in 895, he joined the staff stocking one of the new wings at Mnemthosis, working with portents and prophecies.
At this time the Thoth priesthood thought their role should be more active. Since they potentially had the knowledge to stave off disaster, then it was their moral imperative to do so. In 878, in celebration of Mnemthosis' quincentenary anniversary, new wings were being added. Once of these was dedicated to the prediction of coming catastrophes and how to avoid them. 
In 908 Marcus became the chief librarian at this wing, informally known as Apocalypsis. This greatly accelerated the research, but also brought a certain air of doom to the wing. In 912 Marcus founded the order Salvation, dedicated to seeing the signs of the apocalypse and fight it. 
The increasingly darker prophecies began to worry the priesthood. Kangrisorn remained in the hands of the Ontainian barbarians. Marcus claimed that if this continued, the world would come to an end. Apart from a smaller group of dedicated followers, most of the priesthood thought that this was not the proper way to worship Thoth.
In 930, Marcus traveled to Nulb, a small hamlet in Hardnit, following a rumor of some ancient rune tablets there. He never returned, making his followers talk of conspiracy. Almost immediately after his death, Marcus was declared anathema. Salvation was disbanded, and his library wing was now considered Non Imprimatur, not to be reproduced. From now on, Marcus's name should be avoided, and if one had to mention him, he should be called Marcus the Blasphemer.
In the late 1030's, a lot of events, some dangerous, some more curious, were taking place all over Bandagora. This led to a movement to reopen the Apocalypsis wing for the lower ranks of the priesthood. A trial was prepared for the matter to be debated, but it all came to nothing as the a fire in Mnemthosis burned down that section of the library.
