The War of the Red Plains (131 A.G.E. - 136 A.G.E.) is the name given to the civil war of Faldon, fought between the ruling House of Lennox and the rebellious House of Haldor. It is called such because of the particularly bloody nature of the years preceeding it and the actions of the House of Lennox in their attempts to suppress the rebellion.
Its conclusion at the Battle of Falion saw the House of Lennox fall and the House of Haldor take the throne of the Royal Empire.
