...and arguably Sigvald to Monogod as well. They totally don't fit into the chaos undivided theme.
Chaos Undivided/Warriors of Chaos should just be:
- Archaon the Everchosen
- Kholek Suneater
- Daniel (Daemon Prince)
It's honestly annoying having Sigvald with Nurglings and Valkia with Daemonettes as this is thematically dumb and unfitting of the setting and lore.
Move them over to Monogod so it's two for each Chaos Gods (Slaanesh would have 3 due to Sigvald being moved as well).
WOC/Chaos Undivided would still have 4 lords and this is plenty for it.
