Are these sentences worded in the correct way?

FYI- Aoth is the mage, Bareris is the bard, and Malark is the monk/spymaster. After Bareris and most of the Griffon Legion traveled to Bezantur, Aoth resumed command of the aerial company and tentatively renewed his friendship with the bard. The battle mage also enlisted the help of Bareris, Tammith, and Mirror in verifying his suspicions about Malark. Aoth and Brightwing intercepted a secret message that proved Malark’s treachery, and they then showed the proof of the spymaster’s guilt to Nevron, the zulkir of the Order of Conjuration, who ordered them to arrest the monk.
