Personally I would love to see new sea routes.
Two ideas: a) weaken the strong position Riombara does have. b) enable leapfrogging along the coast.
a) I (a miracle!) agree with Chenier. I would make it even harsher than Fronepu-Rines....for example Fronepu-Ajitmon. This would enable attacks into one direction while keeping the other direction relatively secure. It would be impossible to keep a strong guard in Ajitmon, allowing both raiding and attacks from Fronepu.
b) leapfrogging: right now we have a purely two-dimensional map in regards to travel. To leave (or enter) Riombara you /must/ travel through a long, thin corridor. If travel along the coast would be possible...for example between two rurals, for example in the north: Pella (Thal) to Qonnor (Sint). This way Sint could attack Thalmarkin (or the other way round) without having to march via Old Grehk. Create a ring of sea routes as that and a lot more possibilities open up: Fangor-Watersdown; Aesh-Kraake; Kif-Worvobaen; Eykfar-Shifgregor....and so on, right around the island.
