From publisher blurb:
Being pursued by a murderous war-party of grooth, the Heroes are two days into the chase. They have only slept in snatches, tasted few scraps of food, and are cold, tired, and thirsty. Always, it seems, the grooth war-party is close on their heels. Feral eyes glinting in the near-distance. The PCs are just breaking a hasty camp, when a scouting party of grooth come upon them.
Shades of Yggdar is a one session adventure for Barbarians of Lemuria: Mythic Edition.
