Arborea: Tales of the Golden Fleece

A DnD 5e campaign focusing on interactions with the Greek Gods, the Titans, terrifying classical monsters, and stumbling (rather unfortunately) into a revenge plot long in the making.   Arborea is a plane connected to Faerun through the River Styx, as well as some mysterious circular portals composed of amethyst gemstone. Its residents are composed of creatures and gods that have long since been forgotten in the current age of Faerun. Arborea contains long lost wonders spoken about in the Greek myths of old; the Golden Fleece, the Helm of Darkness, and other all-powerful magic items worthy only to be utilized by the gods.
