[X] Give to Suizhen
The Pearl seems to be the best fit for Suizhen (it even has the same color!), plus I'm curious just what kind of innate abilities she'll awaken. And if there's some kind of hack included? It will be on her and her Fate to deal with it. Still, I wouldn't mind consuming it personally too much, be it for a Cultivation base increase or to forge a Battle Artifact. We might need it fairly soon.
As for the second choice, this one is even more difficult, but-
Hmm. The idea has just occurred to me, but we've been viewing the Ravens and the lich as separate entities, be it as allies or enemies. I don't really know enough about what is and isn't possible with magic in the setting, especially when it starts to interact with Cultivation, but this sentence:
The Bleak Raven Leader critically damaged his personal foundation when breaking through to Reality Forming. Something about the dungeon he is inhabiting allows him to stabilize his foundation, and he is slowly repairing the injury
Reminds me of possession stories in xianxia.
Like, an old ghost possesses cultivator, but has to recuperate because the process has damaged him too much. That the dungeon helps him stabilize his foundations is also hella suspicious, so perhaps it doesn't necessarily have much to do with the location itself, but with
distance? Remember how we had certain range constraints regarding our phylactery before we decided to Go (Further) Beyond. Might not apply to other liches, of course, but it makes one wonder.
There are some things speaking against the theory, like the fact that the Bleak Ravens are still listening to him, but perhaps they don't care who exactly the Patriarch is as long as he's strong enough or don't have a choice in the matter.
So, in light of that:
[X] Assault the Bleak Ravens
Whatever is going on there, I don't want to give them even more time.
