After returning from the Empire, Ainz sat at his desk in E-Rantel and leaned heavily against the back of his chair.
While he had already begun recruiting for the newly-founded Adventurer’s Guild of the Sorcerous Kingdom, it would take quite some time before the results could be seen. Until then, he would have to amply prepare himself.
As you know, the Dwarves in Overlord use runes. One of the CN translators did some digging and found that the JP names for the four Dwarven cities correspond to actual RL runes.
All the Dwarven city names start with フェオ - Feoh/Fehu, which roughly means (mobile) wealth, like cattle, sheep and the like. Probably named for prosperity.
The former Dwarven Capital is ベルカナ - Berkanan/Beorc, which means Birch.
The current Dwarven Capital is ジュラ - Jeran/Gēr, which means Harvest, or a (good) year. The abandoned city to the south where Ainz found Gondo is ライゾ - Raido/Rad, which means ride, or journey. Finally, the ruined Dwarven city is テイワ - Tiwaz, which corresponds to the rune for the god Tyr. Many thanks to 黒輪-san for this information.
