Are these three sentences worded in the correct way?

FYI- Szaa Tam is the lich. Knowing that his army’s victory was inevitable, Szass Tam magically transported himself into the middle of the clash and tried to use the Death Moon Orb to coerce Dmitra, his former ally, into joining him. However, at that moment, the Spellplague occurred and the artifact exploded in the lich’s hands. Significantly hurt by the explosion, Szass Tam made his way to Xingax and ordered the atropal to immediately transport them inside the Keep of Sorrows, which had been completely taken by his forces.
