Actually, Edict E1.2 does not prevent anyone from moving with the fleet. It simply states that during this term, the Heir and his army will go relieve or reclaim Tarsos. Unless the heir teleports to his army, there's enough time for a trip and back to Side from Alexandreia. On the other hand, it would be possible to pick up the heir with the fleet, but that would be bringing our fleet much too close to the Seleukids. I wouldn't recommend moving the heir's army by fleet until we have our new ship ready. But that's just my 2 cents. I don't know how this teleportation thing is supposed to work. Tarsos however, is probably lost, while Side can be defended if it gets a general in it.
