Spent the afternoon in the royal archives. Found a dusty scroll describing the 'Blade's Ecstasy' technique. It's an ancient discipline where a warrior channels adrenaline and lust into a single, focused point. The text describes a state where pain and pleasure become indistinguishable, where the body is pushed to its absolute limit. It mentions that the climax of the technique is reached not just through physical endurance, but by achieving a state of total vulnerability with a partner. The diagrams are... explicit. It requires a level of trust I've only ever felt in the heat of battle. I need to study this further. The application on the body could be... revolutionary.
