Several plots that have been used in Soul Campaign were originally player ideas! So we, at Soul Campaign, encourage players to contact the moderator team if they have a plot they would like to work with! Although we can't guarantee that we'll use all of them, we will do whatever we can to incorporate them into our storyline. This includes character death, mission suggestions (or requests!), NPC related events, player-driven ideas, or something similar!
So if you have a plot, idea, or suggestion that you would like to work out, please e-mail the mods at soulcampaign[at]gmail[dot]com.
