Is this small paragraph worded and structured properly?

Dorn, Pavel, Will, and Jivex traveled to Thentia after the victory in Sossal and reached the city in time to attend the conclave between the individuals who were working to thwart Sammaster’s plans. Although the seekers had made little progress on finding the source of the Rage since they had convened four months before, the metallic dragons, working in concert with a host of allies, had found and destroyed several bastions of the Cult of the Dragon. In addition, they had protected the smaller races from wyrms in the throes of frenzy and from the secondary threats that the Rage had created across Faerûn.
