Re: [Monoceros]
Gather and store food and water, the kinds of things we're taking for granted right now. We won't have a guarantee of them in the future.
Prepare to fight Ophiuchus. Some of them have been freed from King's influence, and will be on our side, but the rest can be taken over by him at any time, and we'll need to fight them, even if they've been our friends before. Similar to that... don't use the real names of any Ophiuchus you might know. Bringing them to our side requires taking their names away, and giving it back can return them to King's influence. Without knowing how many are turned, we'll need to be careful of that.
Prepare meeting places, gathering spots, places we can come together. More than one of them, so that if one is destroyed, we can move to another, and another.
And there are other Judges who are siding with Messenger. There's no guarantee of how many, but we aren't in this alone.
