I have 3 questions.
1) Are they planning to pillage Elfind to pay for the mobilization? I bet the cost is ludicrous.
2) Why not use crew tents with logistics so good? Quick deployment, minimal weight, good protection against weather elements, enclosed tents provide warm shelter considering winter is coming. A 10 sq meters crew tent weights only 30kg, and you can even put a stove into it. Deployment is, like, 5-10 minutes.
3) How old the wife is? During the previous war she looked the same, so maybe at least twice as old as the MC?
