The Stone of Scone also known as the Stone of Destiny—is a polished block of red sandstone. It is thought to be the last remaining part of The Coronation Stone that was used for centuries in the coronation of the monarchs of the Celtic Empire.
The leader of the tribe in possession of the Stone of Scone is declared the ruled of the Celtic Empire. Many uprisings and civil wars have broken out to gain this prized stone's power, notably the Kirkish revolt where a whole eastern region of the Celtic Empire grew tired of fighting against the current holding tribes and instead gained significant forces and political backing to simply refuse to acknowledge it's subjective power of rule. The independent nation was formed with a 'democratic' system of tribal voting.
