At last, Eisen was nearly finished with the main preparation for the Golems, although he still had a few more things to do here and there. For one, he needed to add the 'Information Storage', aka the Brain, into the head as well.
And for that Brain, Eisen had a rather good idea, because it seemed the perfect base for a three-dimensional enchantment. So first, Eisen created a rough oval brain-shape and then began to get to work with the use of transmutation, swiftly hollowing a few places out here and there and using the materials that he used for that to create the actual 'Models' for the definitions and the center.
And the center simply got a small crystal brain, while the surrounding 'Element' spheres got a rune representing the word 'Thought'. After that, Eisen simply placed the brain into the hollow area in the head that he prepared for it, and filled the area surrounding the crystal brain in a potion that was supposed to increase the intelligence stat for a little while.
