Drukyul may be the mining areas (sedimentary hills) coming down from the Urufulu maybe some igneous rocks depending if the plate boundary cuts from the Urufulu into the Eastron The Sekaplami are a relatively short (both in length and height) mountain chain It's likely the remnants of a much older and larger mountain chain, one that perhaps formed when the Aflua-Trokar region collided with the rest of Valar The Sayalami, on the other hand, are gigantic in length, width, and height Likely a younger mountain range formed within the last hundred million years or so, when Nilyaval, Belwald, Dorak, and parts of Vertlea collided from the north *Urarafalu, not Sekaplami, my bad Sekaplami is the Ironcrest mountain (have a private channel where I speculated on west plate tectonics It's likely the remnants of a much older and larger mountain chain, one Nilayaval is similar in shape to Aetar(if you put them together like a puzzle) if theory is correct Nilayaval and Aflua-Trokar may have collided but the Urufulu is likely older then the Sayalami
