Dark Souls

A player character in dark armor wields a glowing red greatsword and engages in combat with the colossal, skeletal dragon-like boss Ancient Wyvern on a crumbling stone structure. The character dodges the boss's attacks, leaps across broken platforms, and attempts to strike the creature's vulnerable underbelly while the massive wyvern lunges and rears its spiked body in a desolate, ruin-filled environment.
