As you stand at the crossroads of tunnels, the faint melody grows louder, swirling around you like a magical embrace. Alke and Grite exchange excited glances, their eyes sparkling with anticipation. Suddenly, a shimmering figure materializes before you, bathed in ethereal light. It is Siegfrid, the Guardian of the Depths, protector of these hidden realms. His voice resonates like thunder as he addresses you, 'Brave wanderer, your choices have led you to this pivotal moment. The fate of our world hangs in the balance.' Siegfrid's gaze pierces through you, awaiting your next move.
