Overall, go around and sack and preferably head to the area you want to settle, build up on the way, get another Armie or leave it at two, do your Tech research, lvl up potential Governers through Retainership etcДЄdvice: before your settle demolish your Horde buildings in your Armies, if it takes 3 turns to get rid of all because you got up to lvl 3 Horde buildings then do so, the money you invest you get alot back, so if you have say 30k already and you invested through time, then your get an additional 20-30k from Dismanteling your Horde camp buildings. The options are varied, but you could also settle in Italy and its Northen part, depends on your personal taste and what recources and City templates for building you want. Realy depends on your playstyle as well, Visigoths are not hard to get to grips with, ofc the ERE is strong, but if you know your suroundings and whats coming its easy anyway, just think your moves ahead.Д«ut generaly speaking your better of going more or less for thier Historical Setteling location, that being Narbonensis or also id say head for Burdogila in SE France, from thier Expand realy. Then again, that's just what I did (on Legendary difficulty), it might have been better decision to settle in Italy, Sicily or even Africa. After you obtain one province you should sit on it and build up your economy and food surplus before planning any conquest. The Western Romans bear little resistance in the region so you're not overwhelmed. I eventually settled the cities of Aquae Sextiae and Narbo in southern Gaul, the lands are fertile there, provide good income and food surplus.

It's wise not to fight the Western Empire just yet but move across their borders and into their fertile lands. My first move was to sack Thessalonica, move through southern Greece sacking those towns then moving along the coastline north and into northern Italy, by that time you will have enough money to settle somewhere. As the Visigoths you'll want to get aways from the Balkan region sooner rather than later, the area is a mess early on with the onset of numerous horde nations, the Eastern Roman Empire can/will put up a decent defense of their lands and the eventual arrival of the Huns will only make matters worse for you.
