You find it difficult to sort out what is in the nests without largely extinguishing the fire.
The humanoid corpses in the chamber include two goblins, a kobold, and one human male who matches the description of the ranger from the adventuring party you know went in here.
Poking through the refuse over a period of
10 minutes uncovers 312 sp, 68 gp, and 3 gems (worth
25 gp each). On and around the ranger's corpse are
several items: studded leather armor, five daggers, a
longbow, a backpack (containing a water skin, one day's
rations, a bedroll, a tinderbox, and three torches), a
quiver with six arrows, a potion of healing, and a pouch
that holds 17 gp. A gold ring (worth 10 gp) on Karakas's
finger is engraved (in Common) with his name.
