In a cathedral bathed in the melancholic glow of vanishing dreams, the Sentinels moved like shadows against the twilight. Their robes carried the essence of lost aspirations, and the space resonated with the silent cries of dreams unfulfilled. Around them, the architecture seemed to mourn the absence of hopeful visions, with shadows and light entwining in a dance of lost possibilities and lingering echoes of what once blossomed in the hearts of dreamers.
