Just killing time reading threads and I just happened to think about something odd:
Tyreen could decide where her powers went. She wasn’t trapped in a Vault like Nyriad to keep them from moving on at random. Do you think she viewed them as a blessing or a curse?
I’m thinking curse. She embraced them, but how much of her posturing about her vampiric nature was a facade to mask how isolating and alienating it was? If that was the case, who would she want to punish by burdening them with her powers?
OK, to even have a chance to suss out a guess based on what we know, there are a few things I think we would need definitive answers on:
Can other Sirens hold multiple abilities, or only the Leech Siren? And if only the Leech Siren, can her ability be transferred to an existing Siren, since it can take from an existing Siren?
Can men actually inherit Siren powers if a Siren chooses them, or was Troy a fluke due to the conjoined twin phenomena?
Why am I even thinking about this???
Because I have an idea that’s spun out of my other ideas:
Lilith didn’t just get her powers back, I think she got Tyreen’s as well.
Parasites hook into a host, normally without their knowledge, and then drain them slowly over time, leading them to need more sustenance to maintain themselves, all the while feeding the creature lurking within.
Tyreen’s powers were significantly oversaturated thanks to the Eridium energy Troy absorbed, that Tyreen leeched from him upon his defeat, and then the energy she leeched from the Destroyer’s Rift. That is why Lilith was able to Phase Elpis.
Lilith Phased Elpis inside Eleezer, which was a vast enough space within space where the Vault of the Sentinel resided. She did this to save Pandora, but also knowing that she had inherited Tyreen’s power, if not some facet of the Destroyer’s as well, and the only way to keep the universe safe was to do as Nyriad had done, and seal herself away in the Vault of the Sentinel with Elpis.
That leaves Ava, Tannis, and Amara as three of the four possible Sirens, excluding the mysterious seventh Siren Nyriad’s writings warn about. With Lilith, arguably the most powerful Siren, out of the picture, now would be the an opportune time for these other Sirens to make a move.
There’s no one on Athenas to protect its Library of Siren history.
Nekrotefayo is no longer a secret, as both Maliwan, & the C.O.V. are aware of its location.
Atlas, Jakobs, & Maliwan are all recovering from the conflict, leaving Vladof, Tediore, Torgue, Hyperion, & Dahl in positions to try and exploit the Eridian technology left on Nekrotefayo.
They cast Cate Blanchett as Lilith. We’re talking Academy Award Winning Actress Cate Freaking Blanchett. They don’t land her without pitching a substantial story arch for her character.
So yeah, TLDR: What if Lilith got cursed with Tyreen’s powers and the power of the Destroyer, used that power to Phase Elpis into Eleezer to seal herself away and prevent those powers from escaping when she eventually dies, while also saving Pandora from being torn apart by Elpis opening the Destroyer’s Rift?
