In search for non-existing secrets.

So I got it into my head that there MUST be something with the golden Idols found in act 3. Surely the words "Golden Treasure lies forgotten in the depths of an ancient ruim rewarding those bold enough to seek it" is not just flavor text right?

My conspiracy primed mind couldn't let go of the idea so I took the six Idols and have been dragging them around looking for a place to use them. (Madness, I know).

Well I'm in endgame now with the fresh character I made to collect them, still holding on to them looking for a place to use them.

The biggest hint, if it's at all a hint, is the ancient ruins reference, so I've been visiting anything that could have qualified as ancient ruins for the vaal empire using my ver meager understanding of the Lore.

I've tried

the cemetery of the eternals (has the "ancient ruins" marker),

the Titans grotto (seemed like an ancient location, thought maybe the titan impaled with a sword was it),

I walked all around Keth assuming it was also ancient and might have something under the sand,

The trial of sekhamas (although not till the end as I'm still too weak) and the trial of chaos (ditto),

Temple of kopec ("the weird checkpoint placement there" I thought..)

The excavation, it's supposed to be a precursor ruin so sufficiently ancient.

Eye of hinekora

I went to the burning monolith and the reliquary vault as well..

All to no avail.

So I'm probably being foolish, but does anyone have any motion of any ancient ruins in the endgame or elsewhere I've missed? I assume it should be ancient for the vaal as well as we found the idols in the past.

I'm pretty sure my hunch is nothing, but I still wanted to source the wider community about this and see if there isn't something I missed before giving up on it.

edit: I will also try to run both full trials (Sekh and chaos) to see if that does anything when I'm strong enough. same for the monolith.
