The weather out there is cold, but it seems it almost floating in the sky. The whole architecture of Ishgard is inspired by what we can call the Gothic Era IRL.

Me, my husband, and our friend observing the Spear at night. Can you also find it when you lift your eyes to the night sky in Eorzea?★-☆*⭑✧⭒*-✦-☆*⭑✧⭒*-★-☆*⭑✧⭒*-✦-☆*⭑✧⭒*-★-☆*⭑✧⭒*-✦-☆*⭑✧⭒*-★-☆*⭑✧⭒*-✦About the DeitiesMenphina The Lover - 2nd month - umbral
Element: ice
She is considered the keeper of the red moon and the white moon. She's Oschon's lover and Azeyma's sister. I wonder if she'll have a role in Endwalker...
Halone the Fury - 1st month - astral
Element: ice
She's the Guardian of the holy Ishgard. She's the daughter of Rhalgr and rival of Nophica (for some obscure reason, I don't really understand why, I need to dig more into it).
