About the Dwarves secrets, I kind of wonder if not trying to rope in Karak-a-Karak first is a mistake :
- The High King, the Runesmith Guild and/or Kragg might see it as a slight,
- Karak-a-Karak is more likely to be the Karak entrusted with whatever remains of Waystones secrets (well Karag Dum might know stuff but...),
- Having the backing of the High King would probably simplify further dwarven recruitment,
- Any collaboration with Karak-a-Karak could help relations between Belegar and his liege,
- We'd get to see where they stand on the waystone project from the get-go and could adjust our plans.
I mean, if anyone knows the importance of the Waystone project and the difficulties it may encounter it's probably Karak-a-Karak. Even if they only give us nominal support, we would at least know where they stand and could then go to Karak Azul.
