Between the ruins of the Second Empire's Capital of Mur, itself built atop the remains of the First Empire's greatest city (very close to the intersection between the Murray and Murrumbidgee rivers), all eroded by time or looted beyond recognition, lies a 340 metre tall construction made out of smoothened diabase; the Emperor's Tomb. It is surrounded by four large pillars at 90 degrees from each other, one of which points almost directly (.3% error) towards the geographic north pole. It can be accessed from a small opening at the bottom. The inside is mostly made up of a number of elaborate tombs, most of which were thoroughly looted beyond recognition. At the flat top, there is a statue of the first emperor. Its inscription reads;
"Neither storm, fire, drought or war,
will ever extinguish the life,
in the artist's work, nor his soul.
I once lived, and brought life to this land."
Radiological records indicate the Imperial Cenotaph is the oldest of all Trinity Monuments, built shortly after the beginning of the First Empire. It was likely a visual display of its authority over the land, and remains a holy site in both Dreamtime and Asterist faith. However, it is also the most damaged, presenting signs of bullet holes, cannon fire and artillery shelling. Were it not for its smoothened construction and the natural hardness of diabase, perhaps a significant amount of it would not be there anymore. The Imperial Cenotaph is also one of the hardest to enter, due to the presence of the Society of Imperial Restoration, which occupied the nearby ruins and use it as their base of operations since shortly after the country's independence. Permits for archeological expeditions are rarely issued, and usually only to the Department of Knowledge, with whom the Society maintains a warm relationship.
