Shadow of the Elves - Season 1 Episode 9 The Lost Gateway

When a gypsy visits the fairy village selling starflower bonnets, everyone is intrigued - for varying reasons. Legend has it, that these flowers only grow by the secret gateway to the lost homeland of the elves. The gateway houses the "heart of stone"' a gem of immense power. This stone can open the final gate only if "two warring hearts are blended as one". Upon finding the stone, Phaedon reveals himself as a power hungry traitor, but accidentally destroys the gate, which Daiman and Thalia had opened. Everyone catches a brief glimpse of the land beyond the secret gateway, before it is closed again forever. The power of the stone removes everyone's memories of these events, and Phaedon's secret is safe once more.
