1) Lothunics party consists mostly from Forebears or ex-Forebears, so it has no sence to add them
2) Restless League is a tiny alliance of pirates. We don't add factions with lesser political and military power than Dunmer Great House
3) Wayrest was raided by pirates near 25 years ago and was already restored
4) Skyrim will be the same Kingdom of Skyrim, ruled by King Thorygg and allied with Stormcloaks, because mod starts in 4E 199, before active part of Stormcloak rebellion. Player, as Skyrim, Empire and Stormcloak will have different choices about how to participate in Skyrim Civil War or even prevent it.
