2 points during Ilberts summoning seems to be important:

- a new god: so the result will be something completely new and what the Ascians wanted to get durin the WoD storyline. Rhalgr should be out by this as he is not "new".
- a god that don't need prayers at all

It also seems that the massacre was part of the summoning. So maybe it can give us a hint. Did you notice the "Answers" melody during the summoning?
Just to expand on this a little:

Ilberd very specifically says he will "become a demon" which implies he either intends to become a primal as Louisoix became Phoenix, or he plans to act as host to a primal as Ysayle and Thordan did. In either case there is heavy implication that Ilberd is not entirely dead. This may explain the two human feet we can see within the closing Dalamud.

As for the prayers, I'm still not entirely sure what's going on there. It's possible that Elidibus taught Ilberd a new summoning technique. We've seen the beast tribes summon via ritual sacrifice before to amplify the strength of the primal so it may be something along those lines.

My current wild theory:

There's also the fact that Ilberd seemed to be emulating the events of the Calamity that led to the birth of Phoenix. When Louisoix became Phoenix he essentially hijacked the aether that was intended for the summoning of the Twelve. There was a faith component, but it was undirected: the people saw the Twelve failed them and desperately cried out for anything to save them. It was Louisoix who chose to take those elements and become what Eorzea was crying out for. It may be possible that Ilberd has somehow hijacked a summoning of Rhalgr to become a new primal himself.
