The air in the shattered Eastern Tower chamber crackled, not with the lingering scent of destruction from Klaus's earlier sparring, but with a new, raw energy that vibrated deep in the bones. Dust motes, suspended in the faint moonlight, danced frantically, caught in the invisible currents of power. Klaus stood at the epicenter, his body a taut conduit, every nerve alight as he poured the boundless arcane energy from his core into the unassuming ring clasped in his hand. This wasn't a gentle coaxing; it was a furious, desperate demand, a torrent of pure will and power aimed at waking the ancient Arkdieu fragment.
