From the hilltops of Alfama, Tomás gazed over Lisbon’s shimmering Tagus, maps and compass in hand. He’d always dreamed of sailing new seas, like the great navigators before him, but the city’s river held its own secrets. One morning, Tomás noticed the currents flowing strangely—dancing in spirals, humming softly. With his tiny boat, he followed their winding path. The city faded behind as mist rose and sunlight fractured into rainbows. The currents pulled Tomás to uncharted islets where birds sang in unknown tongues and trees bore fruits shaped like stars. Each island revealed new mysteries: a lighthouse whose beam pointed straight down, a cove of silent ships with glowing sails, a library carved into coral, holding stories of every sailor who’d vanished in Lisbon’s fog. On the last island, Tomás found an ancient astrolabe and a message: 'New worlds wait for the ones who listen.' When he returned, nobody believed his journey—except for the children who found, on the beach, shells carved with maps and a compass that spun with the tides. Tomás became Lisbon’s storyteller, inspiring dreamers to chase the city’s uncharted currents, knowing that somewhere beyond the mist, new adventures always waited.
