Meaning
Shiro on the meaning of.

"Back in Aria, Asharia had two meanings depending on the word you use with it. The first is Asharia Nilua which means Unstoppable Fortress. The second is Asharia Yuani which means Fortress Utopia. Since this place is supposed to be both a weapon and a safe home for the spirits, Asharia just fit the situation in my mind."
