Alright here it goes, There will be a story going with this quest.

You run into a guy named Stranger and he tells you how forces of amazing power are trying to take over the lands and will stop at nothing, someone needs to step up and hold back  the forces, do u accept?

u can make many quests of this, im giving the idea but i can think of names for the people taking over and everything but anyway...

First you have to defende there incoming attacks, so defeat 30 of the Reapers, once your done with them your ganna have to make a move further and take on 50 of the Soul Stealers, your almost there, to weaken the forces kill 100 of the Imperial Archers, now you face the last 3 forces that will really test your skills, but anyway you end up attacking 3 last guys that run the army, but thats just a sumary i can get more specific and make it alot more intresting that just an idea let me know what you think? u can turn this into 50 quests just have individual things here and there and have the 3 guys at the very end of all the quests.

Wow 

 Why does this sound so familiar?

It's basically outwar

i didnt know outwar had a story line like that,i never knew the story line to outwar, i just thought this sounded pretty good, but i guess i could come up with something new

It's not familiar from outwar. I only played that for a week, and didn't pay any attention at all to storylines. I was only there to see if I could see the items in the game, so I could try to recognize them when players tried to copy them in the old weapon forging system.
