I feel like I'm going crazy.

There was a Ishgard banner right?

Like the other 3 GC banners but blue with the Ishgard crest right?

I vividly remember having it before I changed servers.

Like I understand that currently Maelstrom, Flames, Adders, Ravens, Falcons, Mol, Hatching tide and Rising are the only ones I can find but I swear there was a Ishgard one too.
