A way to end the war with chalced [posible spoilers]

[Liquid Ice]

Well any suggestion to do with dragons or stone dragons is a lil.. iffy. Doubt you should just awaken them or could awaken them at any time you want.

And normal dragons wouldn't fight for humans unless they had something to gain... and even then I doubt they would bother.

Cutting off trade and raiding is an option. Though I think (Not sure) alot of traders use Claced and a meaningful source of income so unless they can profit from something else it wouldn't be that easy to just say "no more"

Also I believe Stage 2 was suggested at one point during the Tawny Man. Kettricken was given alot of gifts and then the suggestion was made... though I don't remember why she declined it... other then it not benefiting them at the current time.
