So Voice/VOID is using a different name and naming scheme with Flighty as Devourer/DODD? Is that to obfuscate things or to denote that Voice is using a different aspect of themself in this situation?
In one of the previous chapters, Voice mentioned a bunch of names in that format (like Destroyer of Destined Dynasties, in chapter 22), given (or perceived) by someone on the losing side of a revolution. Now, it could be that Voice simply has multiple naming schemes* and it doesn't mean anything beyond Alivaril running out of Steam for vaguely fitting word combinations. It could be different aspects, IIRC VOID always starts with Voice, but the DODD one doesn't seem to be as consistent. So my guess it's more that individual anchors (which were mentioned in the SMILE report) get different names, where the primary anchor has Voice**. Voice herself has said that the number of names varies by language, but it's unclear if that means naming schemes or instantiations of the scheme.
*Though at a guess, VOID is actually just one name, but it's such a complex concept that people just see one side based on their perspective and use that. Like seeing only a face of a cube. DODD would be a second name.
**We know there's at least 1 more scheme (EOID, but I prefer to treat that one as EID, German for oath), and also DDODD, which may be different, or maybe Alivaril just put an adjective too much in there***.
***The list of names in 22 includes
Demonstrator of Debauched Desires
Destroyer of Destined Dynasties
Devious Demon of Despised Dreams
Enabler of Impossible Delusions
P.S: While I was going through Chapter 22, I noticed this on the topic of Sunset having a crush on Voice, and Voice knowing:
"Plus, I'm the Voice of Inadvisable Dreams," Voice added mischievously. "If I don't feature in at least a few dreams, I'm clearly not trying hard enough."
Notably, that's Voice referring to herself as Inadvisable Dreams, when she first introduced herself it was Voice of
Imperceptible Dreams, while the chapter of her introduction is
Impossible Dreams.
