Seles Royal Palace, Nidhogg Tower.
Standing at the center of the palace, Nidhogg Tower is deemed to be the landmark of Seles.
This white tower exceeds two hundred meters in height, indisputably the tallest building in the kingdom, having stood for over a century without its record ever being broken.
Legend has it, in order to construct this colossal tower, the Kingdom of Invia expended tens of millions of gold pounds, employed tens of thousands of construction workers, and countless Transcendents took part.
As for the exact purpose of Nidhogg Tower, it remains a significant secret of the kingdom to this day.
Some say it's a spectacle, mere proof of the kingdom's might, with very limited uses, such as astronomical observation.
Others claim it is part of the capital's defenses, asserting that as long as this tower stands, Seles will not fall.
Yet there are those who say Nidhogg Tower is a Wizard's Tower, where the kingdom's mightiest wizard resides.
