After some heavy thought and much debate i have decided to write a quest line for the Thieves guild after the events of Mercer Frey.
This Quest is to take part after being contacted by a man in solitude leading the PC on a epic throughout Skyrim and maybe even Solstheim to find the final resting place (or believed to be resting place) of the Grey Fox.
The PC is sent on this quest while also being hunted and pursued by a fanatic cult of the Grey Fox lead by a Noble in Windhelm. As you get nearer to the truth everything will begin to seem more wrong until you are on your own, and the guild has burned to your feet. To become the greatest Thief you must find the secrets that have plagued the guild for so long, and only then will the Guild become great.
I am no Experienced modder and cannot even make a simple dungeon but if anyone is out there that will be willing to help me make this become a mod i will be happy to lend my services as the story writer
Thank you, Astral
