Silverhall

Silverhall is the capital city of The Martellite Empire. It houses the Imperial Castle, recently renovated to a motif befitting Charles Henrik Ecleziar's justice pursuing agenda.
  Silverhall's walls are lined with a special material that allows magical wards to be inscribed easier. This material gives Silverhall its name, as it bears a gleaming, silvery color.
  Several pre-Imperium conflicts found Silverhall at its center. As a result, the defenses built around have a bold claim to them: they have not been breached since the days of Martin Eleanor, the Empire's founder.
