Эребор
Tolkien wrote most of Khuzdul in the Latin alphabet, and in Cirth within Middle-earth. The dwarves had adopted the Cirth from the elves by the end of the first age, and made changes to their liking to represent the sounds of Khuzdul. There were two methods known of writing Khuzdul, "Angerthas Moria" when the dwarves still lived in Khazad-dûm before its fall, and "Angerthas Erebor" once they fled and further developed the Cirth when they settled at Erebor, The Lonely Mountain.
