I have completed the naval harbors for now. The original descriptions seemed to contain very little relevant information and I'm afraid I may have cut too much in some instances.

Here is the Epirote description before editing:

{naval_harbour_thrace} Neorion
{naval_harbour_thrace_desc}
Hellenic Military Port\n\nA Neorion, or military port is an upgrade of the bay with more space for berthing warships as well as the necessary facilities for building better and larger warships, which will be needed should you wish to defend our shores from our many enemies, or take the fight to the enemy, should they be Romaioi, Karthadasti or the Achaians.\n\nIf your desire is to make Epeiros a great naval power then a Neorion is not enough and larger docks and shipyards will be needed to get the warships needed to control the seas.
{naval_harbour_thrace_desc_short}
Basic naval facilities in this port enable concentration and maintenance of greater fleets

After editing:

{naval_harbour_thrace} Neorion
{naval_harbour_thrace_desc}
Epeirote Military Port\n\nEpeiros needed large military fleets to defend its coasts, protect its interests in Magna Graecia, and to bring war to its enemies, should they be Romaioi, Karthadasti, or Achaians. Military ports, called “neoria”, with larger shipwrights and more docks were built in Epeirote cities to construct, berth, and repair the necessary warships and transports.
{naval_harbour_thrace_desc_short}
This medium-sized shipyard is capable of constructing and maintaining more advanced fleets.

My new Epeirote description seems a bit short but I really didn't cut anything important or necessary from the original. I would also like to now what a more correct Greek version of Achaeans would be. Romaioi and Karthadasti seem pretty Greek but I think Achaians is a fairly English version of the word.
