Are these two sentences worded properly?

FYI- Malark is the spymaster and monk. When Aoth, Bareris, Mirror, and Tammith confronted Malark and tried to apprehend him, the spymaster used a magical stone given to him by Szass Tam to summon several allips, the vengeful spirits of suicides. Malark fled while Aoth and the others fought and ultimately defeated the undead entities, and although Tammith managed to catch up with the monk, he incapacitated her and escaped from Bezantur.
