Izzy's dear grandmother, Ammoolia, was a wise and lively old lady living not too far from the Highlands Grand Orchards. She had planted more fruit trees than anyone in her village could count or remember. In her younger days, she would spend her summers at the Island of Mū in the Deeplands. There's an ancient monastery on the island, dedicated to studying the Scrolls of Mū and tuning into the echo of unity from the dawn of the universe. It's a sort of spiritual order that they maintain there. Long story short, she had significant insight.
