Let's see;
One was the scream of the wind and the force of the driving ice shards, it's power lay in the sky above and to the south of them, where the storm clouds were thickest. Its power was wild and frantic, a thing of wind as much as cold, eroding all before it.
Untamed nature, a being of the sky. Allies with the third on their shared purpose of eroding the world it seems. Stylistically similar to the original wind thief, maybe a bit of revelry. Small risk that it favors the sky tribes and would thus see us unfavorably, but these
should be wild spirits.
The second lay in the glacier which rested in a high cleft at the end of the gorge they had rested in. Its qi was solid and immovable, ten thousand layers of ice laid down over ten thousand years, compacted again and again until it may as well have been stone, carving the stone ahead of it, millimeter by millimeter with every passing winter.
Here's our shot at insight into UGM's future development, the art that's iirc currently planned to become a thematic bridge to Zhengui and the only one of the three covered here where we don't have much instruction/inspiration.
Might be problematic for the same reason the fungus was, not clear from the description alone if this is a spirit of
inevitability or one also of stagnation. Considering the UGM/glaciers angle it's likely just the former and we have nothing to worry about save a blanket refusal, which is a risk with various levels of bad consequences in all 3.
The last reminded her most of Zeqing. It was the purest cold. It lived in the white out, and on the high peaks, dancing with the first spirit as they drowned the world in white together. In winter it descended to blanket the land in life ending cold as it did now. It's power was centered on a low mountain southeast of here overlooking the gorge.
The one most like Zeqing, the purest expression of Cold. These spirits are indeed deadly but they should not be malicious. The question is how would a meeting with one go.
Most likely the high risk/high reward option, because it is in a sense the most personal to both LQ and Hanyi. Conversely, the spirit might not like this odd reflection of its nature that it sees, which would be bad.
Still, worth noting that Zeqing was a spirit of desire, and ultimately both chased after boys (the one that wrote FVM), and even ended up dealing with humans. If this one remains impartial we should be able to offer satisfaction of its curiosity for passage and perhaps a bit more.
With all three spirits it's worth keeping in mind that we're not that far from the area of power for the ice witches in general. I'd say the second is most similar to those from what we've seen of the one at the caldera, but obviously individual cultivator variance applies, and we should ideally pick an option that works both if dealing with a wild spirit and if it is one that dealt with humans (or distant kin) before.
Overall, I think all three have merit, but I find the second and third the most interesting in development direction:
[] Seek the stolid glacier.
[] Seek the smothering white.
(and among the two I'd go for the 3d because I'm a sucker for drama, though the margin is small for this sub-choice)
