From the publishers blurb:
A Fifth Edition adventure for level 3 characters.
The villages on the edge of the jungle used to be wealthy: they gathered fruits and exotic hardwoods from within the jungle and sold them as wines and furniture to regular merchant caravans in exchange for grains and other staples.
But caravans do not make it through anymore. A handful of tattered survivors have made it back to the city and reported being assaulted by wave after wave of panthers that would attack, retreat, and attack again in replenished numbers. The merchant houses want their lucrative route back. The villages need grain and supplies; their people cannot live forever scavenging fruit and huddling by their hearths in fear every night.
Tales lead deeper into the jungle - to the ruins of an ancient empire fallen to a terrible curse.
This Fifth Edition adventure is written by Zzarchov Kowolski (Thulian Echoes, Scenic Dunnsmouth, A Thousand Dead Babies, The Gnomes of Levnec, etc), illustrated by Chris Huth (Ashen Stars, Call of Cthulhu Investigator Handbook, Night's Black Agents, 13th Age Glorantha, etc), and mapped by Dyson Logos (Waterdeep - Dragon Heist, Circle of Hands, Dyson's Delves, etc). It will work with most campaign settings as long as the adventurers are near (or can be brought near) a large mostly uncharted forest or jungle.
