Tiberias Calore IV was the fourteenth ruler of Norta. His reign lasted from January 3, 237 until September 2, 270 NE.
Tiberias IV served as a general in the Norta army before succeeding his older sister, Queen Leonora Calore. He married Nightingale Welle and together they had five children, Tiberias Calore V, Aerik Calore, Tiberiane Tyros, Tereza Calore and Aerin Calore.
Tiberias IV oversaw more than thirty years of war as king. Toward the end of his reign, he began a clandestine campaign against the Kingdom of the Lakelands. He set up a spy network with House Iral to "infiltrate Lakelander strongholds, track troop movements, sabotage supply chains, and assassinate key figures within the Lakelander government and military."
His son, Aerik Calore, was killed in retaliation for one of the assassinations he authorized. After Aerik's death, Tiberias spent most of his time at the front, leaving his first son, the crown prince Tiberias V to rule from Archeon.
