Alias, also known as "The Knight Princess of Iris." The only daughter of the noble family of Arctalus, a prominent clan in Eos.

She holds the position of Grand Master of the Knights of Saint Iris, the main military force of the "First Fortress," a power she earned through her own merit, not her parents' influence.

She is very popular among the inhabitants of the fortress and is highly respected and admired by her subordinates.

She upholds chivalry and is extremely strict with those who have fallen from grace. She strongly rebukes the protagonist.

Although Minister Beardsley harbors inappropriate thoughts about her, Alicia herself does not share these intentions.

"Such a cruel person...this traitor...I will never let that man go...!"
