Also known as the Splendid Forest Serpent, the Dragon of the Barrens, and the Keeper of the Mysteries of the Ssesha
Near the end of many a heroic venture or quest a brave band of adventurers upon return will find it necessary to seek out a sage, a wisened person, looking for the answer to a riddle, to decipher a map, or to unlock a geas or curse placed on one of their own. The strangest of quests, those touched by the madness of the fae, the eldritch influence of the outsiders and abominations, and those tainted by the hellish realms, are best met by the mysterious sage known only as Mugwort.
In the dank,dense areas of the world where the vigorous and the decaying are intertwined and indivisable, lives the wise bagabond. But getting him to impart his knowledge is quite a chore.
The PCs encounter a strange set of artistic drawings done on the ground as they pass through a city. It has been done in chalks and no one saw who did it. Wizards might recognize the writing within the colored square as an obscure and dead language with a message stating that a prominent wizard and a retired bard have discovered how to populate Arcadia with the spirits of the dead!
Is it a local hoax, or are the PCs crossing the path of a very deranged and possibly dangerous mage?
