Where will the Trifarix lead Noxus to conquer from here?

Under their rule Noxus has gone through a number of reforms to better strengthen the empire: tightening their grip on power, putting down rebellions and further expanding the empire in various efficienct ways. From what we’ve seen so far I believe the Trifarix will focus most of the war effort on ‘smaller’ targets : the easy city states and lesser nations. However once these have areas have been conquered all that’s left are the major factions of valoran , all of which have shown or will show heavy resistance that stops any invasion in its tracks So where do they go from here? https://vignette.wikia.nocookie.net/leagueoflegends/images/3/37/Runeterra_Map_01.jpg/revision/latest?cb=20170308222904

To the north is the freljord which has resisted noxian expansion for years with even the most tumultuous of tribes pushing back many warbands and the harsh cold weather making extended invasions extremely difficult to maintain

To the west is Noxus’ oldest rival: Demacia. No nation has resisted Noxian expansion more effectively and longer than demacia. Despite the many advantages Noxus has over demacia (warmasons, assasins, magic users and powerful vast armies), Demacia has always pushed them back

To the east lies another nation Noxus has failed to conquer: Ionia. For now the Trifarix has no plans to invade Ionia again and another invasion could be devastating for Noxus as Ionia now seems to be adopting warlike qualities and will be more than willing to use the full extent of their magical capabilities (both good and bad) to defend itself and might go further and attack Noxus city itself in revenge Bilgewater is a possibility but with its dangerous sea monster infested seas, vicious pirate prowling the sea, and it’s close proximity to cursed the shadow isles ,I doubt it wouldn’t be worth the trouble

It seems the best option is to focus their efforts at conquering shurima and piltover as it has already conquered most of the northern shuriman coast and the advanced technology of piltover would be a game changer in the noxian war effort but they won’t be easy as the piltover will no doubt be able to fortify itself with supreme hex tech weaponary and defenses and considering piltover is biggest trade point in the known world, the clans can ask for aid from many nations and factions the rising war between azir and xerath will see them dividing shurima and whoever claims the northern regions first won’t take kindly to noxian occupation and seek to sever the ‘usurpers’ hold on ‘their lands’

Which ever direction the Trifarix decided to go once it’s conquered all the ‘easy’ targets is anyones guess and they’ll need to implement their three principles( might,guile,vision) with expert efficiency to get past these 4 major roadblocks to Noxus’ road to ultimate glory

And let us not forget the ghost of Noxus’ past setting his sights on his former kingdom
