There were at least three colony sites outlined by someone earlier in the thread, I forget who, and
@Cetashwayo then outlined a fourth. (EDIT: It was
@Spacegnom!) Personally I think the islands in the Venetian lagoon are still the best option.
The argument for this does not need to be made to a broad majority of the thread, but since the reasons why have been brought up:
Rescuing Kymai means we will get both prestige and the undying gratitude of the people we save, as well as establishing a large colony who will be our allies and trade partners, greatly magnifying commerce in their region. If they are next to the Enetoi, the trade routes coming down from mainland Europe will be magnified greatly. A city of seven and a half thousand people is vastly larger than any colony we can establish ourselves, and will boost Adriatic trade. The new city may even become a League member, although I am not banking on that.
Moreover, if you were not inclined to believe me, we have been explicitly told by
@Cetashwayo that there are big potential rewards for rescuing Kymai, along with the real challenges, if it was not obvious. Potentially, there could be something even more exiting. To compare this with subjugating the Dauni is silly because in the medium term they are not mutually exclusive, but saving Kymai
is a limited time opportunity.
The reason I would like to do this isn't just for the rewards though, although they are potentially great. It is because it is big and bold and exciting, and also generous. Eretria is extending itself in a grand exploit to help others, for moral goals and to save people, not simply for gain. That's exiting to me and it's interesting, and I think it will make a fantastic story. Why wouldn't we grab such a grand adventure by the reins, when we can make new friends into the bargain?
