There's storage underneath where the boy was sitting, a huge chest. It contains some food for humans, some fodder for horses. Not much of either, nor much in the way of other camping supplies. There's three cups, recently used, but no sign of stored water. Multiple bundles of something that feels like they might be heavy stacks of papers, wrapped in slick cloth.
Also three thin books! Their titles are Second-Year Fire Magic, Second-Year Water Magic, and Second-Year Light Magic.
