I'm thinking, for no real reason except that I was reminded of it, about Thuron, the Kryn agent the Nein interrogated in the sewers who they initially let take the beacon.
The Crownsguard immediately killed him when the Nein let him go, and they of course promptly stole the beacon back. It's easy to imagine that his soul was captured by that beacon in particular, purely based on proximity. It's not clear whether the case the Nein put the beacon in to avoid its detection prevented souls from leaving the beacon, but let's say for speculatory purposes that it did.
The Nein didn't get that container until the following day, so it is possible that in the time between their taking it and its containment, his soul was bestowed on some infant in Zadash. However, the next place the Nein used the beacon extensively in an urban setting was in Hupperdook, and I think that that's where Thuron should've been reborn, because it is SO funny to imagine that from his perspective when he goes through anamnesis in, idk, forty years.
Like, you're a reasonably high-level drow Kryn agent, probably in the Lens hierarchy, because you were sent with one other agent on this extremely important, very secretive mission on behalf of the Dynasty. You were killed in the streets of Zadash certain you'd failed in your quest of bringing this sacred artifact back to your people. You come to several decades after this and have to process the following:
your death effectively started a war,
the random jackasses who interrogated you and then let you go in the sewers went and stole this artifact back the moment you were downed, for seemingly no reason except impulse, given their otherwise disinterest in messing with the Crownsguard and the artifact itself,
months later they hand-delivered it to the Bright Queen herself, having supposedly walked across the continent,
these jackasses evidently carried it around for a hot minute through a Dwendalian party town known for weapons manufacturing at SOME POINT between these two events, WHILE the war was going on,
and also, you're a fucking gnome.
This has NO business being this funny but god, it is so funny.
