In a world of floating islands connected by shimmering bridges of light, Lyra, a young bridge weaver with the ability to manipulate these bridges, sets out to find the Heart of Light, a mythical artifact capable of controlling the very fabric of these bridges. Her journey takes her across treacherous bridges, encountering rival factions, ancient bridge spirits, and the enigmatic Lightborn, beings born from the very essence of the light bridges. Lyra's past, marked by the collapse of a bridge that claimed her family, reveals a connection to the Heart of Light that could either solidify the bridges and unite the islands or unleash a catastrophic collapse that could shatter the entire world.
