I assume the Factions are identical in functionality to the original Syndicates
So, I've just discovered by buggering about that I can actually craft certain Amulets to ally with other Enclaves; I assume these work like the OG Syndicates where, if I ally to any other, any standing I gain with the Silent Roses I'll lose half as much with the Kith of Kings (my original Enclave).
Unless that's not the case, in which thank god. Because balancing out Red Veil and Steel Meridian with New Loka and The Perrin Sequence is a kind of torture I wouldn't wish on my worst enemy XD
