I don't see Dhara surviving with the current political clime. Sad, but true.
Because of the pathetic Lurian imperialists?
With the northerners coming against Aurvandil, I feel quite confident. For as long as we remain alone against the Lurias, I can see the battles going both ways, but I do not see the possibility of things going really bad, should they go bad.
If Lurians try to sail to D'Hara, we'll just laugh at them when they try to go back home. We've got harbors on the isles and on the continent, they don't. Any attack on our core isles would be extremely costly for the Lurias.
