Empowered by their expanding magical abilities, the Tarutaru united themselves as the Federation of Windurst, and worked to drive the hordes of Yagudo beastmen from their lands. The Tarutaru prospered, unified by their knowledge of magic and the solidarity of a new federation. It was a glorious age for their people.
But revealed secrets cannot be suppressed, and the knowledge of magic slowly spread to all the people of Vana'diel. Within a short time, other races - and even beastmen - began to employ magic techniques for themselves.
Filled with regret, the Tarutaru entered an era of isolation. They closed their borders to all but their longtime friends, the Mithra. And so, a once-proud civilization became more and more out of touch with the rest of the world.
