So I have been planning a TL for a while that is heavily inspired by mobiyuz's TL31 (https://www.deviantart.com/mobiyuz/gallery/64510242/Timeline-31). But I ran into a problem when it came time to pick the pod. the main difference between otl and this alternate timeline is that more states seceded during the civil war. For contact this is the map I produced. note that this is in the year 1860. So to put it simply what kind of pod ( if there are any that can achieve this) is required for this to happen.

Ps: I am aware that Kentucky, West Virginia, and Oklahoma would be heavily contested I decide to give them to the nation that controlled them in 1860. West Virginia will decided to try and leave Virginia for America for those that might point that out.
