Brother Ikarion was a novice cleric of the Triune. He refused to deliver his sisters into the hands of the Primus, a mark of devotion. However, his sisters were still delivered to the Triune through the actions of his friend, Brother Tomal.
Ikarion was executed by a Morlu guard, his remains used as an offering to entice the demonic minions Astrogha and Gulag into assisting Lucion.
