Iskas is a major antagonist in Suikoden Tactics.
A high ranking member of the Patriarchal Faction, Iskas launched a major rebellion on the crown, using the power of Eye Cannons to kill several prominent members of the Imperial Faction, including Emperor Julius; though unsuccessful in his attempt to seize power, his actions helped to cause the downfall of the Kooluk Empire.
A man with very grand plans, Iskas hoped to gain overall control of the Kooluk Empire in SY 309. Iskas set his plans in motion by investigating Rune Cannons in Middleport, eventually finding and securing the Evil Eye with the help of Kyril. During this time, he portrayed himself as a collector and merchant in the field of Rune Cannons. At the same time, he also began establishing himself in the framework of Kooluk, becoming a prominent influence in the Patriarchal Faction, manipulating the group to his ends. He compounded this with the seduction of Miranda, the wife of Martin, Crown Prince of Kooluk.
His hope was that he could use the Evil Eye to seize power, control Kooluk with Patriarchal Faction and use Miranda and her daughter Corselia to legitimize his rule either directly as Emperor or behind the scenes. Iskas' skill in manipulation sent members of the Imperial Faction around Kooluk in an attempt to stop Kyril and his group, who had become increasingly embroiled in the situation, especially after their rescue of Corselia from Caleron Laboratory, which Iskas portrayed as a kidnapping.
When the Imperial Faction was eventually alerted to Iskas' true designs, he quickly took control of Graska and used the Evil Eye to transform both Martin and Julius, Emperor of Kooluk, into Fishmen who later perished. He also betrayed Roget of the Patriarchal Faction, leaving him to be overwhelmed by fishmen outside Graska Palace.
Eventually, Kyril's group managed to reach Graska Palace, however, Iskas quickly fled the scene, heading to his secret facility he had built to contain the Evil Eye. There, he was defeated in battle despite his skill in runic magic. Stunned at his defeat, he called out for Miranda, who turned on him, stabbing him. Enraged at her betrayal, Iskas used his magic to kill Miranda before using the Evil Eye to transform himself into an immensely powerful fishman.
After another defeat, Iskas perished and his body was lost as the secret facility crumbled. His scheme to take control of the Kooluk Empire was ultimately what drove the nation to its destruction.
- Iskas is curiously able to escape from the monsters and the large blast caused by the rune cannon underneath Middleport.
