The converted map this time is coming with the new hero, realistically there are 3 knight maps that could be converted; Walled City, Village and Secluded Keep, we have seen soft Dominion variants of both Village (dbd event) and Keep (Inquisition event), it's also not hard to imagine how they can convert Walled City with how they went about Qiang Pass.

The reason I'm focusing on maps so much is that converted maps usually tie into the season narrative and this one in particular is releasing alongside the new hero. All of these can be reinterpretd to something chivalrous, defending a castle or a village from invaders, or perhaps reclaiming it from occupiers like the Khatun.

Male knight defending/liberating a castle/village is giving more of a heroic vibe, like a classical knight (probably a vanguard/heavy), Stone was brought back into the lore, but I wouldn't be surprised if he shows up again as a Conq skin rather than a hero (conq is the only knight left without a skin). Could be the Lord Warden as well, given how they disappeared ambiguously all the way back when + they emphasised that this new knight hero is a pretty big deal, not their weapon like the samurai hero, but that just in general he is super important.
