Lol, basically, two of the six Factions in game are involved. One wants to expand through any means necessary, Yesha Empire, the other is the target for they have a hold of finances and trading, Mercantile Guild. So far, there are a few groups involved trying to stop this plot, one in Yesha, the others already in the Guild.
If that is too much, you can always start off in Anvala at the Burning Skies Saloon, Cathedral at the Wild Winds Inn, or at Chang-ning at the Crimson Skies Saloon.
