The Demon Palace

The Demon King's castle was located deep within the demon realm in a city known as 'Gorthalon'.

Gorthalon, a sprawling fortress city built into the rugged landscape of the demon realm, was a place of dark majesty and foreboding power.

In the human texts, Gorthalon was described to be the mountain where the first Dragon King had once built his lair, as it was a mountain situated on-top of a massive natural mana vein and was arguably the best place in the entire landscape of Terra Nova to reside and practice skills as a warrior.

However, as time passed on, it was the demons that had conquered this mountain from the dragons and it was the first Demon King who had built the magnificent palace that stood there today, which every subsequent Demon King had used as their base of operations.
