Are these three sentences worded correctly?

FYI- Shadovar and shades are the same and the Hall of Shadows is Shar's temple. Telamont commanded Yder to send the Hall of Shadows’ guards to join the Shadovar forces waging war against Cormyr. Yder followed his father’s orders, but since the Hall of Shadows would be vulnerable after the departure of its guards, he sent several of shades with him to protect Shar’s temple. Yder and the remaining shades then began to once again pursue Kleef and his companions, and to increase their chances of success, they began to work together with the growing horde of orcs seeking the Eye.
