Are these sentences worded properly?

FYI- Cyric is the god, and the group is the Chosen and includes Malik. The group was ultimately brought to a river that would lead them to the Underchasm. At that time, Cyric magically spoke to Malik and ordered him to help his comrades deliver the Eye of Gruumsh to Grumbar’s temple, but then murder the other Chosen at the exact moment of their triumph. By doing that, Malik would enable Cyric to complete a magical ritual that would spread strife and betrayal across Toril, providing the god with further power and guaranteeing him a high position in the divine hierarchy.
