Didn't we destroy the golem's organs? I can't quite remember. If we did, we'll have to repair them first. Not sure how much time it'll take to figure that out. We could study it while the sanctuary wears off.
Yeah, you're right. We impaired its eyes and one of its legs. My suggestion is to use alter golem to repair the damage we caused while using command undead and the ability to remotely control and alter the construct to do so without Eko realising we did it. After all, the curse was able to manipulate the construct remotely too... Although now that I think about it, I think I have a better idea.
Tell Eko to go gather our things from the camp. Even if we don't know what we're going to do, we know that whether we leave or stay here, we're going to need our supplies. So it's better to do something than do nothing. Tell him we'll stay to look after Omo and try some more things. That will give us an excuse to stay with him alone and an excuse for not having all of our MP.
Now, when we're sure he's gone, we need to use Alter golem to repair the construct's eyes and leg, hopefully making it mobile again. Then we cast command undead to it and use those necromantic distance sensing things it has in it to maintain remote control over it. We should leave it playing dead so that Eko doesn't suspect anything.
We can also do some experiments during that time if anyone has any good suggestions, but I think it would be better if we just saved our MP for later.
Then comes the hard part. We need to convince Eko that following the presence we felt in the golem is a good idea and we need to either stall long enough for the sanctuary to wear off or convince Eko to dispel it. For stalling, we could do some useful things like build some sort of stretcher for Omo (maybe add some blankets to keep him comfortable) or search for some extra food. I also bet convincing Eko that we're desperate enough to go after the presence we felt in the golem and that that presence might be our hope for helping Omo and finding the other missing souls might take some time. Maybe we could also talk about how battles between magic users usually work. If we can't stall for that long, then we can probably tell him that we think it would be better to dispel the sanctuary because we think there might be some necromantic spell in Omo that's helping keep him alive, maybe a way to slow down the troops it was meant to intimidate by making them take care of those without a soul for longer.
If we manage to do all that without complications, then the plan is to go towards where the golem was going, using the image in it and any tracks we can find to help us find the tree, while the golem tries to silently follow us from a safe distance through the magic of remote control.An alternate plan would be for us to say that the golem got repaired on its own while he was away and that we want to follow it to wherever it's going to find the other lost souls and whoever it's controlling it, but that sounds much less likely to convince him. Not to mention that Eko might get suspicious when the golem starts having trouble "remembering" where it should go.
As always, if you have a better idea or anything at all to add, do speak up. I'm just one man, there might be something I'm forgetting or my plan might have something stupid in it I'm failing to see.
