You see a dead explorer.
Location
Lion's Rock, Kha'zeel Dragon Lairs/Tiquanda, Underground Glooth Factory, and (only during January of each year) in the Ancient Temple near Glitterscale.
Notes
An explorer has died here, leaving nothing but a skeleton. Perhaps it holds something valuable.
Looks the same as a Skeleton (Item).
One is part of the Lion's Rock Quest, another is part of The Great Dragon Hunt Quest, a third is part of the Glooth Factory Quest, and a fourth is part of the First Dragon Quest.
