[X] We cannot simply lay low all our allies when we see fit for the sake of empowering one man. He is capable, it is true, but the people of Rhyps have done nothing to deserve being turned over, and their fear keeps them well in line. There is little fear of them turning away from us, so why give Harpos a further boon so quickly?
Part of the reason why we were even able to subjugate these Peuketii in the first place was in that they were bickering and disunited. King Harpos now has all but the least of those cities behind him. For the time being, I think it's safe to assume that his interest lies in being fully acknowledged as the unquestioned king of the Peuketii and bringing all of the relevant cities under his rule. Presently he sees us as a means by which he can achieve this, which is why he's willing to not press the issue to stay on our good side. To a certain extent we can expect for him to have good behavior unless he starts seeing his ambitions as being easier to achieve by some other method. I think that for the moment it may be prudent to not let his ambitions drift higher by dangling Rhyps out of his reach until he can do a bit more for us, but if he does us some heroic deeds and Rhyps still stays maddeningly independent then the offers of the northern king may become more tantalizing. I can't help but feel that whenever he does end up with Rhyps such an ambitious character won't feel content to play second-fiddle to the Greeks who devastated his people, though.
[X] Dispatch Kallias north to Arimnus and then on foot throughout Padanian Etruria on the road to Atria to build allies against a potential Liburnian incursion, as they are growing bolder every year and could potentially strike at Eretria.
Most relevant threat out of all of them is the Liburni, as much as I would like to set up in Metapontion. The death of Tyrant Gelo is going to be causing huge turmoil in Sicily and everyone with ambitions there, and while we could play a role with our huge population of refugees from that area and religious influence that's really something that we'd be intervening in rather than the other way around, at least for the moment. Korinthos is concerning given that they are not pals with Kerkyra but given that they strongarmed us into our current alliance we're not really either and would fight more out of obligation than any true passion... as Korinthos really does not have much of a bone to pick with us at the moment, I think that even were they to flatten us in a war that they would pretty much be trying to bring us and our dependent cities in line with propping up their Adriatic ambitions more than like scorching us from the Earth.
The Liburni, on the other hand, are out for our blood. Their pride stings from the humiliations heaped upon them and they remember well the raids we launched that devastated their cities alongside their hated rivals the Enetoi. Their is no doubt that they seek our destruction, and the presence of pirates on the Adriatic Sea is absolutely devastating to us; that discourages traders from taking to the seas, and that jacks up the price on basically anything to be had from Hellas and beyond tremendously as well as starving our info networks.of news from over there. Plus, our calming of the waves enabled some pretty impressive ahistorical Greek colony-planting in the area which allowed us to expand and assert our influence with not much more effort than playing a big brother to the inevitably smaller & weaker northern settlements; keeping the barbaroi of the area weaker makes it easier for sparks of Hellenic civilization on the frontier of the world like ourselves to be sustained by pushing that scary frontier farther away from us.
[X] We need to have the wall fortify the shore and harbour, so that we are protected against naval raids and assault. [-270 talents, wall will protect the shore and harbour, three turns to build].
Marginally superior growth rates are no good if we suffer a naval sneak attack while campaigning out in the Dauni Confederation or somewhere and half of Eretria gets burnt down; we know aside from that that the Liburni are looking for revenge. It only makes sense to have a defensible harbor in light of this concerning threat.
