Bab 2519: Underground Fortress (Part 1)

'Merfolk have gills that allow them to extract oxygen from water and could pass me as much air as I needed just by taking deeper breaths than usual. Underground there is no air, instead, and Nalrond has to keep a low-pressure area to draw oxygen from above and then split it between us.
