Violetta and Lucky: The Fourth Gate

Fire, Lava, and the Deepest Regrets.
Violetta and Lucky escaped the illusions of the Cloud Castle, but their hottest trial awaits: the Fourth Gate and the Golden Fire rune.
Their objective: the Cauldron of Molten Light, where the Crest of the Unbroken Heart is hidden.
But the path leads through a scorching canyon where the mere thought of failure ignites an actual flame. To pass, the heroes must learn to accept pain not as a destructive force, but as a cleansing one.
They will face the Guardian of the Fiery Core - a creation of ash and lava. He does not use lies, unlike the Whisperer. He shows Violetta her deepest regrets, trying to convince her that her friendship with Lucky was a mistake.
Can Violetta and Lucky pass through the flame of self-doubt and prove that their Loyalty is stronger than any fire? Or will the Crest remain forever in the Cauldron, dooming the Balance to ruin?
