so while playing skyrim i got fed up with having to go via either the sewers or the graveyard hidden passage to get to the ragged flagon to hand in or get new quests for the thieves guild

So i made this quick fix.

It places a trapdoor in riften on the wall besides the graveyard and outer wall
and one in the columns of the ragged flagon for quick access .

Grab the key inside the thieves guild and enjoy the shortcut!

DISCLAIMER : The open cities version is untested at this point and might cause your follower to disappear for short periods of time.
