Is this small paragraph worded and structured properly?

FYI- Szass Tam is the lich, Malark is the spymaster, and the southern legion serve the Council/ mage-lords. Shortly thereafter, Szass Tam used magic to infiltrate the Central Citadel in Bezantur in order to speak with Malark. By revealing why he had murdered his ally Druxus Rhym, the zulkir of the Order of Transmutation, in 1375 DR, the lich persuaded Malark to betray the Council of Zulkirs and join his cause. Instead of openly switching sides, Malark continued to serve as Dmitra’s spymaster, but used his position to damage the mage-lords’ cause. Malark revealed the southern legions’ plans and dispositions to Szass Tam, guided them into traps or into the path of dangers created by the Spellplague, and sowed disaffection and mistrust among the officers and soldiers.
