Romeo and Juliet. It was a departure from the more expected adventure design of the time in that violent solutions to problems aren’t an automatic path to victory—inquisitive minds and compassionate
hearts carry the heroes further than strength of arms.
This updated version of the adventure reimagines Caerwyn and Porphura’s—originally Porpherio’s—garden as the Eternal Garden, a domain in the Feywild, and the Green Man as the Gardener, the benevolent archfey who rules it.
