Are these sentences correctly worded?

FYI- Aoth is the war mage and Malark is the spymaster. As the Council’s forces continued to be defeated and suffer setbacks, Aoth spoke with Malark and his enhanced sight showed him the spymaster’s face turn into a naked skull. Aoth realized that Malark may be serving Szass Tam, and although he and Brightwing then began to deliver dispatches throughout southern Thay for the Council, the war mage planned to try to find evidence that confirmed whether or not his comrade had become a traitor.
