Larian's comrade-in-arms and friend, Jiles, received a family heirloom in the mail: a pendant from his deceased grandfather. Then he lost it during a night of liberty in Mirasol, a town near their Company's camp.

Larian agrees to help Jiles find his lost heirloom. Their search brings them into the heart of Mirasol's underworld, where they encounter dangers they did not expect during a simple night of liberty.

Grandfather's Pendant is a 8,300 word novelette, and is the fourth of Larian's adventures. His earlier adventures are chronicled in Michael Kingswood's earlier stories: How NOT To Rescue A Damsel In Distress, Measuring Up, and First Blood.
