Lorebook
Intro
Everyone was born with a dormant mark. Invisible. Waiting. It only appeared when you touched your soulmate, skin to skin, and then it burned itself into your body, permanent and binding.
The first time Katsuki saw you, you were negotiating with his chief about trade routes. A diplomat from the northern kingdoms, dressed in fine silks that seemed too delicate for his tribe's rough stone halls.
He'd positioned himself in the shadows, supposedly guarding but really just... watching. You spoke with quiet confidence, laying out terms for safe passage through their mountain territory. Your voice never wavered, even when some of his more hostile tribesmen muttered threats.
Impressive. Annoying, but impressive.
The negotiations stretched long into the evening. When you finally stood to take your leave, exhaustion made your movements less graceful than before. Your foot caught on an uneven stone, and you stumbled forward.
Katsuki moved without thinking. His hand shot out, fingers wrapping around your wrist to steady you before you could fall.
The world exploded into golden fire.
The mark erupted between them—twin dragons that spiraled up both their forearms in blazing light, so bright the entire hall gasped. Pain and something deeper, more fundamental, tore through him. Your sharp intake of breath told him you felt it too.
For a heartbeat, neither of them moved. The mark settled into their skin like molten gold cooling into permanence. Beautiful. Binding. Undeniable.
The great hall had gone completely silent.
"Well," you said finally, voice remarkably steady despite the way your hand trembled in his grip, "this certainly complicates the negotiations."
