there is nothing left to protect that way, everyone is dead unless you cooperate (and at this point you have to use a ram an expand and 2 more actions to just about make it at the last second)
Fippe pretty much admitted it, but chose his words extraordinarily poorly so I doubt that will convince you. So your enemies are the fire and the lords, though the lords wont really do anything regarding your faction, as they milked what they wanted from you and worry about other things now.
Also fippe you can closely compete with ryli for the cultist actions. If you really dont want diplomacy know that you are playing the game wrong, it will be a race of who posts closest to the deadline (and dont forget to PM CO beforehand with the same actions). Only succeeding twice will result in survival (and you will loose since you are usually not active at the deadline), so try your best to get on Rylis good side instead.
You have to:
Action1: Expand r22
Action 2: ram r22 north
Action 3: deploy rctc in r22 en route to r19
Next round:
Action 2: Detonate bricklaying bomb in r19
Its also essential that the bricklaying bomb remains in the cultists posession.
