It is ideal for authors, worldbuilders, and tabletop game masters. The craft of alternate history is in the ripples — following one change logically through politics, technology, and culture to a believable new world.

FAQ
what is alternate history
Alternate history imagines how the world would differ if a key event had gone another way. Changing one turning point — a battle, an invention, a discovery — sends ripples through everything after, creating a setting that feels both familiar and strange.
how do i make an alternate history believable
Follow the ripples logically. Trace how the single change would affect politics, technology, and culture over time, building a coherent new world rather than just renaming things. The best alternate history feels like it really could have happened.
how do i ground the story
Focus on the people living through the consequences, not just the grand events. A character navigating the changed world makes the alternate history feel real and human, while sweeping summaries of altered timelines rarely engage on their own.
