What? I'm really confused as to what this is supposed to mean?
In the message I replied to, reiterating the "you found it, you don't own it" thing, you were saying that "Everyone on Dwilight knows Brom Silverfire has Brom Silverfire's aegis, which just happens to have historic Zuma significance," as opposed to "Everyone on Dwilight knows Brom Silverfire has the Zuma's aegis."
This was all in the context (as I understood it, at least) of Lurians knowing why the Zuma might want to hunt down and/or kill Brom.
Thus, who Brom thought the true owner of the Aegis was wouldn't matter in this case.
