The Supermassive Eternal Soulsphere

Behold, The Supermassive Eternal Soul Sphere. (Or for short, Soul Birch). The Soul Birch is essentially a combination of a Birch World and a Soul Sphere, and it is made through the "Realize the Grand Design" decision on the Void Birch. It requires the technology to be researched (Souls Within, Souls Beyond - which is possible after Runic Precursor Adaptation), as well as a huge amount of alloys and Perfect Runic Energy. The Soul Birch (as well as the 5 technologies beyond that) is under a special research category: "Eternal Technologies". These have a native research penalty of -300%, so there's a chance you won't be able to research them at all if your research speed isn't high enough. (201%+) One last thing. The Soul Birch is extremely absurd. Unfathomably so. I would very much recommend this if you're a fan of big numbers, or if you're running crises and challenges that require this kind of production. Nonetheless, please enjoy the mod! <3
