There's a brief errand on the way out.
Shifting to a practitioner's second sight for the first time since arriving, it looks like an ice spirit did decide to stop by the improvised bait. Its appearance is distinctly not humanoid; more like a few connected mounds of snow and ice with spindly attachments that might be analogous to limbs. A small elemental, but strong enough to be better than nothing. Now to catch it.
It's settled in enough to not flee as soon as it gets noticed, but it's probably not about to be metaphorically eating out of anyone's hand either.
Amber circles around it, low to the ground and drawing in the snow with a talisman taken from around her neck. Having the heat elemental back would be awfully convenient, partly because it's freezing out here and mostly because it's more effective to bind spirits with their opposites. After getting all the way around, she touches her pendant to the circle and charges it with power from her water and air elementals. Hopefully the target is docile or weak enough that it can be bound by similar forces as well as opposite ones; water is about as similar to ice as anything is, and she's pretty sure the wind that accompanied this air elemental when it was free was a cold one... this is kind of tenuous. But it does react when the circle gets completed, and it does stop at the boundary, so it's probably at least temporarily bound. Or at least not trying very hard.
She starts talking. In the new language where she can; her voice isn't going to reach far enough to be overheard anyway, and it's not as if nature spirits pay attention to the exact text of the human-language words. Or nonhuman as the case may be. "My name is Amber Atreides. You've accepted the offering I left, I returned for you, and now I've bound you. Now I want you to do something for me. These people are planning to trek across the ice, and they need help. I can show you one of them, her name is Irissë. I'll ask how a certain person knew about a recent human invention, the person I ask is her. I want you to keep the ice from breaking under Irissë, give her handholds when she's climbing, help however you can without being seen. I'm not asking you to go anywhere not frozen." Ideally she would have been binding an elemental powerful enough to make a way for the entire host, but in this short a time even this was lucky. "In exchange, I'll break the circle and give you as much of the energy that drew you here as you would have gotten if you stayed an hour. Or I could strengthen it, come back better equipped, and tighten the binding until you have to obey me."
It's an elemental. It doesn't understand what she's saying, in the human sense, but it gets some impression of what it's being asked. But it doesn't indicate an answer; instead it changes form from ice to snow and back and sloshes around the interior of the circle. It moves surprisingly quickly and occasionally stands upright, but stays inside the circle.
