From the publisher's website:
The garrulous old bargeman waited until his listeners were gathered on the deck, then he began to recount the ancient legend: "Once, before the canals were built, this was a great nation, a coastal nation, whose sea-ships fared far and wide across the world. It was ruled by mighty and wise leaders. The greatest of these Coast Lords was Noldes Bartarigan, called the ‘Emperor Who Turned His Face Skyward’, and the ‘Lord Whose Voice Becomes the Sun’. He was entombed up there, on the plateau, in an ageless tomb, provisioned for all Eternity."
Face of Mars is a Savage Worlds adventure for three to five characters.
