'I am sure Lágsaith wishes to regale you with the tale of our expedition, so I will not keep you for long. But perhaps knowledge of the sewers' layout will allow you to appreciate her retelling more.' She hands you a map that has been sketched in a careful hand. 'I traced our steps while we were down there. Lágsaith would never admit this, but she needed the help; her sense of direction is atrocious.
'You may borrow the map until Lágsaith is finished with her retelling.'
