Formed by the Elder Tree itself — grown from its own roots, then transformed with copper drawn up from deep within the earth — the Great Cauldron rests in one of the Tree's hollows, its swirls glowing softly with root light. Beneath it, no flame burns. Instead, magical ember crystals glow with warmth of their own. Wonderlings' magic flows through the roots, but circulating it all through Whimsywood is no small task — so the Whimsykin help too, adding what they've learned to the cauldron each time they gather what a potion calls for and see the brewing through to the end.
