Skull Elf
So the story is getting more and more confusing, either I fail to read and interpret text or the author just throws words at the paper hoping the make sense. From what I understand, Rand Empire is from another dimension and somehow ended up here. So he found a suitable emperor to rebuild the Rand Empire in this new dimension? The reason he got weakened during the training is because the cube needs to use his own energy to scan/study this new dimension?
