Well, now that I have my campaign page more or less how I want it (still have a few background things to add, but it's mostly there) and the game is underway, I thought I would see what people thought of the story line I've come up with. The setting is my homebrew campaign, with some elements from both 3.5e and 4e D&D. I also will be incorporating 3 pre-built games over the course of the campaign. Despite some of the stuff in there, the game is played entirely in 3.5e (for example, some of the gods, and monsters). Well, without further adieu, I give you the "current campaign":http://www.obsidianportal.com/campaign/melekar/wikis/current-campaign in the Melekar Chronicles:
The ultimate end to this story will be to confront Vecna in his tower at the center of the plane of Pandemonium. He has designs on usurping the power of the Gods, taking it all for himself, and to do it, he'll use anyone, step over anyone. Trapped within his tower on Pandemonium is a great Primordial known as Timesus the Black Star, and Vecna is using its power to fuel his own.
The PCs begin the story with Ember being sent to Highmoor, into the care of Alecar. Their first night in town however, the Archbishop is murdered, and Alecar is asked to investigate. He hires Solaren to help, and they managed to find the villain behind it.
The first enemy the party will face is Garreth, once a proud member of the council of elders, he found a mysterious black scroll in his chambers one night (a scroll of Mauthereign, open grave 215) and after reading it, he began to become a little... off. First he simply became irritable, then prone to violent mood swings, and finally we see him as he is today, plotting assassinations and taking control of the council. Eventually, if he wasn't stopped he would eventually invite the Cult of Vecna into power in the council, and it would be a dark day for Luness. For now, he is simply power hungry, and following the tenets of Mauthereign, committing evil to show evil the wrongness of its ways. That is why he wishes to take over Cumberland, and then he would set his sights even further if he were not stopped. Garreth fled after being convicted of murder. He has gone to join Cumberland to stamp out Luness, who has betrayed him.
From there the PCs will have to contend with the Cult of the Yellow skull (storm tower), which is being used as a tool of Mauthereign to collect the 13 golden skulls, and destroy them, freeing the demonic essence within them (they really only want to destroy the one that has trapped an aspect of Orcus within it).
The PCs are then asked to take the golden skull they found in the Storm Tower to the Luminaries to see if they know of a way to destroy it. They offer to take it and try to find a way to do that, but in the mean time, they hire the party to investigate Slaughterguarde, cue The Shattered Gates of Slaughterguarde adventure module.
After returning to Fallcrest, the party dicovers the town to be in bad shape. It's quiet, subdued and empty feeling. The Temple of the Yellow Skull has been sending raiders to find the remaining skulls that are supposedly dotted around the country-side, and anyone that gets in the way (or even SEES the cultists) is brutally attacked. Captain Faringray once again calls on the PCs for help to take them out at their temple once and for all. Discarded in the bowels of the temple they find another of the black scrolls (although the party doesn't realize it, but this one failed, as the Prelate had already fully succumbed to the evil in his heart).
After dealing with the cult of the yellow skulls, the party is invited by Panzanzabon to join the adventurer's guild. While enjoying a rest and stories of the Unvanquished company, an emissary of bahamut is sent to Fallcrest to inform the PCs that Garreth has returned, and he has an army behind him. Cumberland, Garreth, and the Golbin King have joined forces and are coming through the mountains to attack. Their first target appears to be Wellspring, so that's where Luness's forces are going to gather, and the PCs have been asked to go with them. Cumberland moves to attack, along with Garreth and the Goblin King.
