Down to the Ruins!
An excellent choice, Adventurers!
Head right and follow the cobbled path down, passing around - Or maybe even under - the barrier in your way. Follow the path as it veers right and turns to dirt and you will eventually come across a big hole in the ground, encased in stone. Feel free to peer into it's murky depths, Adventurers, but do no more than that! Linger to long, and the four-fingered filth goblins that dwell within will take an interest in you!
