Surely the Yuir gods smile upon us. I have discovered that a wizard in Veltalar named Aldaron the Loremaster has translated a ritual from the Tome of Twilight Boughs. This ritual, when used at the right time at an ancient Yuir ruin, can imbue the casters with great power, allowing them to become the embodiment of the Yuir gods in Faerûn. You must procure this ritual at all costs and use it while there is still time. When you succeed, our cause will truly be unstoppable.
