I have heard that hangul and Mongolic script are related, which might explain how the king was able to create a fully featured beautiful script like that in one go. https://en.m.wikipedia.org/wiki/Origin_of_Hangul https://en.m.wikipedia.org/wiki/Origin_of_Hangul "However the character 古 gǔ also functions as a phonetic component of 蒙古 Měnggǔ "Mongol". Indeed, records from Sejong's day played with this ambiguity, joking that "no one is older (more 古 gǔ) than the 蒙古 Měng-gǔ". From palace records that 古篆字 gǔ zhuānzì was a veiled reference to the 蒙古篆字 měnggǔ zhuānzì "Mongol Seal Script", that is, a formal variant of the Mongol ʼPhags-pa alphabet of the Yuan dynasty (1271-1368) that had been modified to look like the Chinese seal script, and which had been an official script of the empire." Might be true, might be not. Still interesting to see. And the Mongols themselves mostly stopped using their script to write in Cyrillic and Hanzi (?) now so. We have another example of such great men creating a new script by himself after exposure to another script.
