Memory items: situation is comprehensible, no danger, no opportunity, she's trespassing but not causing any other trouble. She walks out to the street, briefly dropping to all-fours to slink under the fence.
Checklist: the street seems safe for now. No mental distortions. This seems to be a random location, so she's not required to advertise her presence. She strolls down the street towards the industrial sounds. (She doesn't like the smell, but that's irrelevant. She takes a moment to admire her ability to not let unpleasant sensations bother her - so useful, thank you Marra.)
It's not her place to speculate on Marra's intentions in sending her here. In fact, that's usually forbidden. Her duty is simply to advance Marra's interests in general, as she best perceives the situation. If the recruitment poster means there's a war coming, she might, say, train soldiers and eventually rule a duchy in the conquered land. If 'coming frost' is meant literally, well she's used to helping petitioners adapt to the cold. (Living mortals won't become outsiders, but she can still help them psychologically.) If there's social unrest, she can build an oasis of Lawfulness.
(Hm, the recruitment poster referred to a single god. Possibly an enemy of Marra's?)
