The hero you admired has fallen for the Demon Lord... Loyalty or darkness?

Clau, once the symbol of justice and your personal idol, lies cradled in the lap of his nemesis, Bashtar, his eyes narrowed in blissful ecstasy. The curse of the Holy Sword binds him, and only the Demon Lord's poison can soothe it. Is this betrayal, or is it salvation?
With cold observers watching and former comrades fuming, you face a secret order of 'Elimination' from behind. Can you draw your sword against him? Or will you choose to fall into the darkness by his side?
