The only way I can think of to find faction accessibility aside from spamming character creation is checking the archetype files individually, which also sucks. Pirate Coalition doesn't really sound like my work, if it is, it's definitely for the pirate mod which is in the mega-mod.

Edit: Factions predated organizations, organizations are a much better version of what factions were intended as which is why the full potential range was never finished and they did not make it into Chronicles. So, organizations to not grant access to factions. Or at least they shouldn't, unless Raven did some backwards compatibility he didn't tell me about.

There were cases where Raven actually put in bits of files or assets that I myself couldn't edit in the game (yet) that would only be used if you had my mods/work that hadn't been implemented yet. 99% sure that's entirely how Monk was developed, as some kind of weird Frankenstein's monster. Just to clear up why I mentioned the pirate one could be related to my mod, though I'm pretty sure that's a Raven thing.

Oh, ok. Thanks for the response. What is the mega-mod you're talking about?

Gurrflumfr's Mega-mod in the steam workshop of Erannorth Reborn. It's okay. Most of the archetypes in there are from early on in Reborn's development, but some (Primarily dragonkin I believe) were updated to be in line with the final DLC.

The Pirate Coalition / Pirate class isn't available in Vanilla Reborn. The best option for playing a pirate in Reborn is Gurrflumfr's mod.

There is a comprehensive list in the Player's Manual for Chronicles regarding archetype changes from one game to the other.
