Here is a truth read from the bark.
The spike of Ada-Mantia, and its Zero Stone, dictated the structure of reality in its Aurbic vicinity, defining for the Earth Bones their story or nature within the unfolding of the Dragon's (timebound) Tale. The Aldmeri or Merethic Elves were singular of purpose only so long as it took them to realize that other Towers, with their own Stones, could tell different stories, each following rules inscribed by Variorum Architects. And so the Mer self-refracted, each to their own creation, the Chimer following Red-Heart, the Bosmer burgeoning Green-Sap, the Altmer erecting Crystal-Like-Law, et alia.
But of all the Prismatic Mer, none were more presumptuous than the Ayleids of the Heartland. They built their tower in open emulation of Ada-Mantia, using as Founding-Stone the great red diamond they had uncovered: Chim-el-Adabal, said to be crystallized blood from the Heart of Lorkhan itself. (For the Heart on its arrow passed over the Heartlands, birthing one of that postnymic's quaternary meanings.)
Thus did White-Gold become Tower One. As all know.
