You know when. You know where. You know what happens next.

The question is whether that's enough.

Drop yourself into any moment in human history — a battlefield, a royal court, a burning city, a pivotal negotiation. Bring whatever you carried. Use whatever you know. Meet the people who made history before they made it. Change it. Break it. Try to survive it.

No fixed universe. No protected timeline. Every era. Every war. Every turning point. Yours to rewrite — if you're careful enough.

▸ Define your own era, location, identity and equipment ▸ Full historical accuracy — real figures, real politics ▸ Modern items seen through period eyes ▸ Language barriers, cultural friction, real consequences
▸ History pushes back — ripple effects tracked ▸ All characters adults (18+)
