Edge island

I'm continuing. I reached the Conflux. I tried to defeat the orange player; it worked, but the losses were too great because he has Armageddon's Blade. I decided not to bother with him, especially since I found out that I can't build a Grail in this Conflux anyway. I reloaded, and freed Catherine from the prison where she was being held. Here, Samatron, you have another minor mistake, which (unlike the first one) should be fixed: the Guardian of the passage, which requires killing Nagash, can also be bypassed. It doesn't matter to me; I already killed him!
A frustrating point: do you think it's okay that the orange player immediately attacks Catherine? Luckily, I split her army into 7 stacks and managed to escape, and then hired her again. And, as it turned out later, not in vain: she has an important role to play! But again: you gave her 5 skills right away, but there's no earth magic among them! So, I'll have to "guide" her, waiting for the right moment, because meeting Tur-Resh will be fatal for Catherine...

So... it turned out to be easier to move Catherine to the underground: I gave her the City Portal from the main hero through a Tan, hired specifically for this, with literacy (of course, after upgrading his skills). Catherine, from the plane of mages, went straight to where she needed to, opened the path, and I collected the reward - at least this time it was adequate! I defeated the turquoise player, practically without losses - Merist couldn't even help with the Alliance of Angels and the Sphere of Inhibition.
Now I'm looking for the purple tent. I looked all over the map - I couldn't find it. I had to open the map in the editor. Of course, it's hidden! If I had known, I would have visited it earlier - I was already there! - and now I have to travel to the same place for a week!
Okay, these are minor things. I'm afraid that Flight or Dimension Door can only be learned by building a Grail in the Conflux at the purple player's location - but I buried it in my capital a long time ago! Then I won't be able to continue... True, I saw a scroll that the blue player must have taken. By the way, the blue player dug up the Grail buried in the underground, so I won't have another one.
