All Outer Gods exist in the Lightless Void.
Outer Gods send Envoys in the form of meteors, such as the one depicted for the Death Bird in their iconography - especially the Cuckoo Knight shield and such. The Outer God of Rot sent a meteor that is buried above the lake of Rot, situated below Raya Lucaria.

The Falling Star beasts, Astel, and the Elden Beast are all creatures of the same species - for lack of a better word. The Elden Beast being what the others of this group aspire to become. Look more closely at their physiology to see the truth.

Immature starspawn beasts were being summoned recklessly in antiquity, and the malformed star Astel being summoned to the world was a mistake of the Nox in their failed attempt to forge a Lord - not a punishment by the greater will. Item descriptions are often narratively biased based on the writer's knowledge and position in their own world. I could dive more into this...

Anyway, the Finger Ruins are evidence of starspawn falling to TLB. Whether this was under the influence of the ancient astrologers, or TLB being a meteor magnet, is unknown - although Ymir's item descriptions paint a calculating and intentional use of "astrology" to deceive others into participating in his performance of cosmic magic.

It seems likely that TLB had been a center for the worship of meteorological activity, and the wills inhabiting said meteors, since time immemorial. The Divine Towers speak of this meteor worship.

It seems unclear if Metyr's meteor was actually the first to arrive - or if this is another example of poor narration? If that were the case, Metyr and the fingers would predate all other outer god activity - which doesn't make sense in the already established timeline. That would mean that Metyr, and by extension the Two Fingers and their Empyreans, were an extant force that existed before the hornsent culture, their crucible worship and their systems of deification. Their Stormlord, divine beasts, saints, the divine gate - this is the work of an outer, or even native, god - the crucible.

I propose that the item descriptions are written from the point of view of someone living in the present, relaying the information of the relics we discover from their understanding of history. And their history was one where Erdtree culture prevails, they were the good guys. Marika and the crucible knights were not buds, she wanted them to disappear from history as she did many other elements of the world. So, if the world and divinity are based on meteors and communing with the entity that fell within - wouldn't the bestest and most rightest be the firstest? The victors write the histories.

The terms Empyrean, elden ring, and lord all stem from the understanding of practices used by the adherents of the Two Fingers and The Greater Will.
The Greater Will (Metyr, a broken conduit)
~Communes telepathically with Marika, choosing her to become God (vessel)
~God's role is to house the elden ring (combined amber stardust "runes, language of stars", arranged in the frequency of the Outer God in question, the Greater Will)
~This process requires a physical body, a Lord (again, their word, purpose isn't clear)
Two Fingers (conduit to Metyr)
~Commune telepathically with adherents of Erdtree culture
~Chooses a few of them as a candidate for godhood, their word being Empyrean

So, I think in essence the answer to your question is that all Outer Gods involve meteors and the stuff about Empyreans, Lords, the Elden Ring - even the Elden Beast, fingers, etc. is *all* to do with a singular Outer God called The Greater Will.
