Are these sentences correctly worded?

FYI- Netherese and Shadovar are the same, and the comrades and companions are the same group. The comrades was able avoid the orc horde and reach the Underchasm, but as they were making their way across the series of bridges and earthmotes that led to Sadrach’s Spire, a castle above Grumbar’s temple, their pursuers caught up with them. Kleef and his companions managed to kill the chieftain of the orcs, deceive the Netherese and orcs into turning against each other, and cause a chaotic three-sided fight to erupt. The group used the confusing clash to escape their enemies and then hastily fled to Sadrach’s Spire, but they could not enter the castle since the entrance was heavily barred.
