When a great mage shows up, Rubèn's first instinct is to yell at them for the damned mess they've made of the countryside. All sorts of travelers making all sorts of trouble, the clerics gone missing and now there's rumors of monsters sniffing about the place, and everyone's worried about the price of food- Which might be good for him, if his fields actually get taken in.
Of course, he's not stupid enough to actually mouth off to a teleport wizard. Even when he grows more and more incredulous as they explain that they want from him. Yes-ser-thankyemuch and all the rest.
He can at least guess at how to play Good. Rubèn's a smart man, he is! Knows how to read, sort of. He's just worried about his wife and kids (mostly about whether they'll sell off his valuables, animals, or crops in his absence) and any consideration they could provide so he can see to his duties with a clear heart would be lovely.
He doesn't want to strain the wizard's patience, so he packs in a great hurry, chiding his eldest to help. Everything he can think of that's valuable, and then as much food that's going off soon as he can in a great big sack. He wonders about his buried cache and whether anyone else might find it and decides not to risk checking on it.
Not ten minutes later, he goes back to the wizard and solemnly declares that he's ready. Hopefully the whole thing doesn't end up in riots and massacres like he's heard of Galt doing.
