Are these two sentences worded in the correct way?

FYI- The Cavus Dun band are Shadovar and consist of Bol and the other five. As Drizzt and Dahlia were traveling toward Neverwinter, the Cavus Dun band beset them, and during the fight, Entreri arrived and helped the two companions defeat the Shadovar. Bol, Parbid, Horrible, and Jermander were killed, and the Shifter and Ratsis fled to the Shadowfell.
