If it's just the hezrou, the fort can maybe handle it with some casualties but no serious operational consequences, but hezrous are only mostly solitary and you can't rely on demons doing what they mostly do. The commander gives the order to read off a Sending scroll calling for a strike team before he heads out to be ready to meet the thing in battle.
She hops off the table with she's done and goes back to eating food and offering flavorings and conversation.
Tap, tap, tap, tap.
The weirdest food she's ever had was a fruit salad with soy sauce (heavy on melons that got soaked in the soy sauce) paired with very bitter and spicy meat, which is a bit tricky to map into rice and beef but she does her best.
Venn laughs. "I'm still not sure if the cook really had a thing for extreme flavors or if she was pranking us, but she ate all of her portion and looked like she enjoyed it!"
She nods agreeably.
After dinner requests dry up, she'll go looking for Lt. Espina to swap notes on demonology. (She knows a wide but not very deep variety of things about the most common demons, but does have some useful anecdotes about scarier things she's seen when being called in and heard in the garrison's mess hall.)
She'll get everything Venn knows about hezrous, which is mostly the standard stuff but a few odd tidbits - how they fight in groups, their surprising intelligence given their actions, etc, and similar facts about many other uncommon demons of strike team tier.
Venn is willing to stay at this until she runs out of demon facts or one of them needs to sleep. (She's also got Invisibility, if Espina wants to do practical demonstrations.)
Venn does not have a wizard's flexibility with her spell slots but won't push the issue.
She heads to bed, spends some time playing with her harp and thinking about the people she's met here, and eventually falls asleep.
The next morning she does her mealtime Prestidigitation routine and waits for the injured to be gathered so she can heal them.
(...Pretty much, yeah, she does not say because it absolutely would not help.)
How's the fort morale (and gossip) this morning?
Grim. They are on the whole in their Chelish way glad that she is there but they are only borrowing her for a couple weeks and nobody's gotten Pharasma'd and people are trading disparaging remarks about whether anyone in the fort is the slightest bit "like the Commander's Abadaran pal" or "like that Gozrehn from last summer" or "a wizard who's also got any common sense".
...Makes sense. Well, she'll do what she can while she's here.
Abadar class! Abadar is the God of positive-sum trades, the creation of wealth, of cities. He is said to keep in his vault in Axis with copy of every piece of mortal writing and art, which Venn finds delightful.
She doesn't know as much about Mammon but she does her best! Abadar cares a lot more about the creation of wealth than the acquisition - building things that make it possible for people to become rich. He's called the God of Walls and Ditches, and some people think this is unflattering but walls and ditches are really important...
