The deep barbarians took and freed themselves. They do not come after the group this day.<br/><br/>The canal that weaved its way through the ancient ruins.  Comes to a small lake that is fed at the other end by runoffs that leading into it.  Runoffs that no doubt come from the surface.   How far these runoffs go is unknown.    So them being a way to reach the surface.  Is not quite feasible.  One would have to hold their breath forever how long.<br/><br/>The party is able to move beyond the Angler worm, avoiding it.   As there has been no signs of it in over a day.   As the party has continued traveling on.   With it taking all day to get around the lake and to the other side where the drains are.<br/><br/>There is a good spot to camp.
