The Black Towers

[Morningstar1337]

Only one that doesn't have a direct Lunar Eidolon counterpart is Ravana. Maybe that's to leave room for more originality for FFXIV dev team, or maybe they'll surprise us with Lunar Asura given she also has multiple arms and weapons.

I'd have a feeling that if Lunar Asura is involved, then there would be a Tower in Bozja, and if that is the case then we wills ee several other towers scattered about first to to spoil that twist.

That said I do think the Lunar Primals if they do exist might hem towards either iconic summons of the ARR primals,so Lunar Gardua, Lunar Bismarck and Lunar Odin are as likely as Lunar Ifrit, Lunar Shiva and Luna Titan.
