And now I'm one of the most vocal pro-Bosporus expansion people in the thread
But nah, all I'm really looking for here is to force the Trelli into quiescence so we can shift our focus back to the Lowlands and the ST without them obstructing trade for a while. Basically, try and beat on the Trelli before they dominate the Not!Aegean and start getting even more ambitious.
And frankly, if we play our cards right- we're not going to be fighting the descending Trelli alone- we're buying just as much Tin as the Trelli if not more at that point from the Tin Tribes
and we can supply them copper at a bargain for domestic bronze production- all along a route nigh impossible for the Trelli to interdict (GS to New TP). Combine that with generally further improving the wealth of the region and possibly sharing some innovations and there are good odds we can at least get some local tribal auxiliaries to back us up. Especially because if we
do get driven out of the TP, their access to a lot of luxuries like; glass, dye, fine pottery, gems, and wine actually
diminishes. Slaves are something they can probably acquire more of on their own with enough bronze- there's plenty of people in land in the Not!Danubian basin, but we can establish ourselves as their lifeline to luxury goods that the noble mine owners are going to want.
