Kaian is right, the "marriage" was just a sly diplomatic move to feel out the other tribes, which is why Alca was chosen. She's beautiful but not really a shining example of femininity, which the eastern tribes prize higher than even the western ones (at least for marriage. A girl is allowed to "be a man" and a man to "be a woman" in the east, but if you do you're not allowed to get married if you choose that path).

"Who's a sneaky-" you begin cheekily, but Ulla smacks you on the top of the head.
"Ehh... Alright then. What about Alca and me? Is she still off to investigate the East Tribes?"
"There's no need now. With the Fallen Star we need all the ears of the tribe as close as possible, so we're even recalling wanderers and diplomats. The other tribes are doing the same, all the way to the Farlake." Says Ulla.
"My scouts have returned as well. We think more stars have landed near every large body of freshwater in the area. Save ours. Ours landed in the Southlands." The southlands are... well, to the south. They're a badland that goes, as far as you know, forever into the south, until it runs up into the edge of the world, or into a land of the dead, or any other set of rumors. Several goblins have attempted to cross it, but only one returned, and only because he broke his ankle three days out and destroyed his foot getting home.
"We were just discussing this." Says Amma uselessly, " I was saying that maybe we should send out someone to go take a closer look."
"Amma, as your best friend for fifty three snows, I have to say that you are the most useless conversationalist I've ever seen." Says Ulla-sha.
Amma blushes. "I don't get out much."
Ulla snorts. "That's obvious." She looks at you again. "Your little date with Alca-un's going to have to wait. We've more important things to do. If you have any questions, ask them now."
