I discovered this last night and thought they could have done a lot more w/ this location...esp since it's very unique in the game.

Thoughts?

yeah, i thought there would be something about rune (guy from the theives guild) down there, but i havent found anything

It just seemed like there could have been ghost bandits or something down there besides two chests w/ some gold. It was a big letdown.
And I wish there was more intereaction w/ NPCs and they would send you on quests to places yet discovered.

I have found 327 locations, but finding new ones takes forever at this point.

I wish there was a quest using the trench, now it just seems like a small but pointless easter egg
