Hey guys,
due to certain ... events, I'd appreciate a conceptual advice on next step of a trio of hags in terms of their powers. Here is their past so far:
- started as 2 hags, were hunted by villagers, took refuge in a large bog
a decade passes
- got smart, got stronger
- started to use their powers in a cunning way
a decade passes
- narrowly escaped pursuers several times
- became really good at evasion/illusion
a decade passes
- perfected a Village ritual, where they would slowly lure/curse a small settlement, then feed off off all the misery
- got A LOT of power from this as traveling dispensers of madness, misery and death
a decade passes
- their power got so strong, they managed to create a own demiplane/domain of dread
- traveled the material plane in ethereal form, scouted villages and have planted Village curse on them remotely
a decade passes
- Got themselves A little sister - a 3td coven member
- further upgraded Village ritual - ritual now actually sucks the settlement into hag demiplane, for tasty morsel to be then picked apart at covens leisure
several decades pass
- Coven encounters Mikolash, a Pale man - a priest of rather obscure god that delves into corruption of children
- a small shrine to this deity is erected near hag hut in the demiplane
- special "playrooms" are built. hags find torture in them exquisite. More acolytes join Mikolash
several decades pass

What would be a good conceptual step for them?

thanks
