Where did the concept of Ravana come from with the Gnath?

[Soge01]

I thought I'd ask this because I'm genuinely curious about it. He's the complete opposite looking to the more infiltry looking Gnath and is far more aggressive, too. Could Ravana have been based off of an Allagan construct of some sort, like how the Ixali were with Garuda. Or could Ravana simply be like Ifrit and Titan: some sort of god/protector they conjured up in their minds over the generations until it became a cult-like part of their religion.

Well as far as in game lore stuff goes, there's the Phantom Rays of the Allagan Empire who are wildly similar in appearance, and there is also Arbuda in Temple of the Fist. It could be that at some point the Allagans came in contact with Ravana, and then designed their construct based off of him. Or reverse the roles.

As for how primals are shaped up, well, all it takes is a legend of a creature and then enough prayers and aether to make it real. Doesn't have to look like the race at all. As far as primals being derived from other beings though... Ifrit looks like a larger, more fit version of a Hapalit/Ogre. Garuda is basically a pretty Ixali that can fly. Titan literally works like a Qarn golem, and also falls apart and comes together like one. Ramuh looks like a duskwight sorcerer hermit. Leviathan is an overgrown Tatsunoko.
