Aias (アイアス, Aiasu) is a Great Knight and aide to General Caellach in the army of Grado who appears in Fire Emblem: The Sacred Stones. He was formerly a part of Caellach and Joshua's old mercenary group from Jehanna and claims to both be a great tactician and that he was never even scratched in battle. Even though he says he has no need for rank or title and is dismissive of Caellach's desire to become a king, Caellach convinced him to join up with Grado as his lieutenant. He is charged by Caellach with killing Eirika, but if the player passes the turn limit, he will flee to Jehanna Hall where Caellach will kill him after claiming he is one of the things keeping him from his future life as king. He drops a Knight Crest when defeated.
