The So_us Monument, nestled atop a gigantic boulder embedded in a canyon wall, was the first indication that humanity may not be alone in the universe. It is so-called due to unfortunate damage to the inscription thought to bear its name, leaving a gap in the purported translation. Although the primitive society that inhabited it was long gone by the time humans got there, tiny details remained and are still being studied. Little else is known for certain, including the true name of the settlement or the nature of the lifeforms who lived there.
