Following verysimilar format for content than season 2
Fangs & Thirst DLC 1 (three things useable by rulers (gothic or vampiric themed aesthetically example a draculesque cape, and two things more) and a new society trait, this new trait could be: vampiric society, this makes any ruler goberning a city a functioning vampire, the population are cattle, and the non gobernor heros are Ghouls or half vampires if a ruler rules once a city stays as vampire, rach wpuld have different bonuses, this is the more flexible way to add vampires amd expand later with vampiric tomes during this season. I let devs decide how should be this basic vampire society trait)
Haunting Cults DLC 2 (Two new forms: batkin with no wings, and Myconids or mushroom folk with heavy witchy or hags looks ), + Intrigue Events now launched and directed by player, new culture: Masquerade, could be gothic cultists with rogue and espionage gameplay, Four new tomes expanding on vampires, castles, hags, and werewolves. The Hags tome could have a spell transformation into white and ghostly nine tailed fox-spirit (kitsunes), amd dryder transformation New mounts, new realm templates, new music, new themed monsters)
