cult of the undead and plants

The cultists noticed how the enemy was again burning tree branches and tearing up flowers and grass for the sake of their rituals, and decided to stop them at least while they were not on their territory protected by the wicked.
You both want to resolve everything verbally, but the ardent nature of the enemy participants, just as ardent as their leader, quickly turns the conversation into a quarrel, and the quarrel gradually turns into a fight between the leaders of the enemy cult. Something needs to be done to avoid killing each other and ruining your relationship even more...

Let's imagine that it's now somewhere around the year 1700.
You are the head of a cult. You worship Satan, wickedness and the animal world.
There is also an enemy cult that worships nature (or rather plants), as well as the undead.

(uncleanliness - the bodies of the dead, raised by unclean spirits and harming the living.
Undead are originally living otherworldly beings or people reincarnated as them.)
(In short, evil spirits are ghosts, like monsters under the bed, and the undead are mythology, like witches and wood goblins.)

Your members are not really enemies, only the most loyal to you and the cult are actively against the enemy cult.
