Fall of Rigasha
After weeks of magical disturbances over the Shrine of Keena, a great portal was opened, and almost immediately, giants began to pour out and overrun the Nezumi. Nothing could stop them, the gate remained open and there were always more. It was the beginning of the Arrival of the Giants.
Master Yao-Rasha eventually returned to the ruined nation, astride a black dragon, and together they gathered a few refugees and escaped via the Shadow Realm to the Isle of Bambos. There he revealed “lost” Orith-Tia teachings to them.
