Rhalgr the primal?

[Belhi]

Is it even possible to forcibly summon a deity as it is with Primals? I may be wrong here but I was always under the impression that the 12 let their presence be known on their "own terms" if you will. As far as we know Primals can manifest when there is a high concentration of aether and/or through summoning rituals. It would seem odd to me that Rhalgr, a deity could be summoned by similar means. If this is not the case, why didn't the Ishgardians call upon Halone?

Well a primal summoned member of the twelve wouldn't actually be one of the twelve. Primals are basically manifestations of their peoples beliefs, only given from by those beliefs and Aether. We don't actually even know if its possible to summon a member of the twelve in some way. In fact we don't even know for sure if twelve really exist.

Just when I thought I knew at least an ounce about primals. XD

I'm actually very confused why these new (theoretical but probable) depictions of Rhalgr are looking Hyuran? Other than Koji's explanation for Hyuran Shiva statues being attributed to Hyuran sculptors.

They say Ahldbhar was the mightiest of the twelve Archons. Rhalgr the Destroyer himself, taken form in Roegadyn flesh─a bloody mountain of a man, and a fearsome warrior, besides. Not unlike our friend at the Coliseum, eh? You must’ve seen renderings of Rhalgr at some point─in paint or stone. Looks like a bag of angry muscles in a mage’s robes, right? Aye, well, those are done in the likeness of Archon Ahldbhar.

In case you're unfamiliar, Rhalgr is the guardian deity of Ala Mhigo, which is currently under Garlean rule. It's highly uncommon for folk of other nations to revere Him.

So if most paintings and statues of Rhalgr are said to be in the likeness of Archon Ahdlbhar throughout the 6th Astral Era and worship of Rhalgr is almost exclusive to Ala Mhigo, wouldn't it stand to reason that it'd be Ala Mhigans who would be carrying on this 1500 year-long depiction into the modern day?

It's a bit harder to tell on the Spire card, Rhalgr's profile looks strikingly similar to Ramuh's model, with the notable exception of rounded Hyuran or Roegadyn ears meanwhile Ramuh has long pointed ears, likely a byproduct of the Sylph's interpretation.
