The lamia

[Rocl]

While the naga / lamia in general are considered Voidsent... ah, no. The Drowned Wenches and Drowned Courtesans in Sastasha HM are heavily implied, though not outright stated, to be normal women that were overexposed to Leviathan's aether and mutated like everyone else in Sastasha HM. Remember that Captain Madison used to be a normal Hyur, and then in HM he looks like god-damn Davy Jones?

Yeah...

They just share a model / skeleton. That's all.

Ah, but my entire response was based off an interview with the team behind the Lore! (As Moose backed me up so graciously.)

You're right, Ceana theorizes overexposure to aether and repeated tempering has caused the people of Satasha (Hard) to mutate. It's important to note Ceana only sees Madison's corpse, though I doubt her theory would change much had she seen a lamia. However, that leaves us at a loss to explain Allagan Lamia; and I'm not about to so quietly buy "they just reused the model lol" when Koji-Fox has stated that the quest specifically draws on deliberate misinformation. I had a fun theory that the Lamiae were created by Allagans by overaspected a person's aether (since that seems exactly like the kind of crazy experiment they'd do) before the E3 interview, but when a reputable/primary source gives us information it'd be rude to ignore it.

Who knows what horrors the bio-engineered naga/lamia were subjected to under Allag rule to cause them to cry out "Don't look at me!"; who knows what drove them from the only home they'd known for the last 5000 years (Dalamud) to Satasha. The obvious answer is to get slain by the Warrior of Light, naturally. An Allagan chimera tempered by a Primal is an interesting thought, but if such a thing were possible (and who's to say it isn't) then the idea of stocking Dalamud with chimeras as a security force was a really poorly thought out plan (and who's to say it wasn't).

Food for thought: a monster known to have a gaze attack (Petrifaction) tells you not to look at it.
