Ples: fighter-enchanter
Lock: merchant-artist-alchemist
Ment: fighter with a two-handed weapon
Heroist: historian
Another Heroist: crossbowman-rogue
Yet Another Heroist: ???
And again, Heroist: ???
Siver: medic-tank
Ney: fighter-medic
Nebo: archer-scout-hunter
Aretz: stealth fighter
Total: many strong melee fighters, many stealthy guys, and medics. No full-fledged mages, a leader, or a linguist(?).
The party conceptually:
Ples: ???
Lock: pagan merchant
Ment: Geralt fanboy
Heroist: heroic baron
Siver: beautiful and righteous knight-slave
Ney: ???
Nebo: true neutral
Aretz: evil knight with a skeleton
Total: only one orthodox character, and even he is a slave. The key characters are an aristocrat with a penchant for heroic epics and a wealthy slave owner. Nebo and Aretz will fit into any neutral or negative company. In general, given the romantic nature of the Heroist's character, the Ment's great quest, and the fact that the church is definitely not thrilled with us, it turns out to be something in the spirit of romanticism: rejection of monotheism, a craving for the epic, and exceptional characters... Yes, the option of tying everything together with a couple of the most colorful and charismatic characters, well-known and having certain key "points of intersection" in ideas and characters, and then attaching the rest of them individually, should work.
For me personally, there are two main builds left: the Aeshean – I'll give him leadership, and considering the religion bonus, he will fit well into the triumvirate, and in general, the vagrant motif should overlap with the worldview of most of the party members; and the Elitarian, who will be quite equal in status to our baron and wealthy man, and if the nomad was a kind of guide for our squad in its escapist campaign against bourgeois everyday life, then the Elitarian is more of an ideological inspirer, which the Heroist's baron will most likely be, but in a mechanical sense, he is less valuable: this is either just a very fat fighter, or a not-quite-leader-linguist with money and slaves. You can also make a necromancer, but I don't think he will fit into the squad as well.
