So a while ago I read this pretty longish timeline with a POD where there were no humans in North America. Thus, the Viking settlement in Vinland survived, leading to colonization of North America in the 1200's. Other things I remember are a Venetian merchant monopolizing the spice trade in the Caribbean, the accidental invention of the compound bow to stun terror birds, which was later used against the Mongol invasion, and Roger Bacon as the English ambassador to China. Now, i can't find it, and I was wondering if anyone else ever read this TL and could give me a link. Thanks, all!
