Hamanu plans to take advantage of the freed but weakened states by marching his army through the Tyr region and conquering all that stands in his way, starting with Raam. He has bullied Tectuktitlay and thus the army of Draj into serving these ambitions.
The party, for their part, has proactively assaulted the Drajan forces and even successfully took out Tectuktitlay. Unfortunately, Nike discovered that Hamanu was waiting for them to defeat Tektuktitlay and had to rewind time to prevent Hamanu from using the slain sorcerer king's energies.
The party's plan is to use mind link to negotiate with the Drajan army and get them to go home so Hamanu has to besiege Raam alone. This succeeds, allowing the party to successfully defend the city and send the Urikan army packing. They then use Tectuktitlay's essence to create a new enormous tree in the city, blessing it with health and prosperity to undo the damage the strife had caused the city
