Why cant Neh simply open another gate, or several smaller ones?

The mega-nurse smashed the stones.

If the dissolving nurses arent completely defunct, why wouldnt they start attempting to chew on the Fae beings that arent tainted if theyre nomming a mana shield?

The free demons eating the mana shield are either calamari leftovers or freed nether from the collapsing mega-nurse. In regards to demon targeting, shields have a greater mana concentration than the drow forming it, so they draw demons more readily.

If the huge gate Ariel and Co are presumably using to summon them is still functioning and producing more nurses, why arent they stopping the ones eating the shield since theyre now becoming a threat?

Next, the gate can't produce corporeal nurses without host bodies. As such, the mega-gate must not have been used, but rather she asked the nurses to protect the tower from the unauthorized gate.

Why arent they stopping the conflict period? Shouldnt the Nidraa be able to ask for help even more readily than random guests?

The nurses would have happily assisted the Feldian forces, but they didn't ask. Also, after the gate was demolished, there wasn't much time before they started to come apart. Lastly, Ariel had activated her blue class secure access key.

More importantly, why aren't those nether demons going straight for the biggest source of mana in the area--the ship's core?

Detection based on the Inverse-Square Law? Demons prioritize proximity?

Chiri is not wrong but I have a feeling of any demon type those nurses would be most likely to let themselves be sealed.

Nether demons without hosts have been portrayed as little more than starving feral beasts. As such, they don't always go for the biggest, juiciest, tastiest-looking spot of mana they can see. They go for the spot of mana that looks like it's the easiest to get at.

Drow? They move too much, and tend to fight back, maybe later.

These shiny rocks? Hmm. They look juicy, they're not going anywhere, they're not fighting back... why not?

This big, honking mana-shield, that's right in front of us? Gimmee, gimmee, gimmee, gimmee!

That giant mana core, way, way up there? Too far away right now, and wE ArE StArViNg!

Any questions?

Provided that the nether essences of the nurses aren't fragmenting into numerous, incoherent demons.
