Ketrab II

I'm going to need a lot of help on this one. I know the ending pretty well, but the begining and middle are pretty blurry.
 * Party makes truce with new leadership, Scotticus is the new harvester. They go to the woods to investigate the attacks on corruption mining operations. Encounter Treeants.
 * Help Treeants destroy the mining ops. Meet Davek, who helps them out too. Also find those mind controlled dinos that Scotticus and Zombor ride.
 * Vandroiy and Sekhmet become big stars in the Arena. They get attacked by a lich after a bout. Lethe gets them to help her kill the arena master.
 * Probably jumping ahead here, but the party attacks and kills Umir. Surkhan gets mad and leaves his position. Scotticus becomes new regent.
 * We go to the forrest and come up against the corruption plague, that has been turning people into husks. Also battle some corrupted plants. I think Kelva came and kept almost dying.
 * Scotticus and Zombor meet with some members of the senate, who are unhappy a foreigner is running the city. I don't remember what happened after.
 * All the while Surkhan has been prodding Vandroiy to rule with him, and getting refused all the time. Sekhmet has been agreeing that he would make a god ruler.
 * Lazari is a lich. I'm pretty sure that gets revealed much earlier. Party fights Surkhan, who is killed, but his energy takes possession of Sekhmet, and flees.
 * Doc Brown returns as a disciple of the Big L'rrrch. Lao is sacrificed so he can reform in this plane. L'rrrch kills the Lazari lich. Vandroiy lures Surkhan out of his body and into his. Scotticus is mutated and flees the city. Vandroiy and Sekhmet are thrown into magma, killing them and Surkhan in the proces.
 * Melisende and Laythe lead the party to perfom a ritual to resurrect Vandroiy. They fight through Surkhan's followers, and raise the fallen ranger. But it is conditional, he must accept the regency of the city.
