Rancoromachy

The Rancoromachy was a massive rebellion staged by the  Ran'Cor against the Si'Gean Empire. Official records no longer exists, and so factors such as death toll and dates have been lost, although a large number of sources indicate the outbrake of the rebellion being contemporary with the beginning of the last era of the Omni Empire. In an immense victory for the Ran'Cor, the fallout from the final battle (The War of the Burning Moon) resulted in the eventual disintegration of their oppressors.
