It seems that to reach the necromancers, you need to run across the water from the red gate (I noticed this while using the editor). But I haven't found the Helm of Chaos yet, and the author mentioned that it's somewhere in the swamps.
I'm also curious about who defeated the ifrits at the obelisk behind the black gate, and when and how. Technically, I could have gone there a long time ago, but because of the cursed land, I need to bring a lot of cyclops and archangels. And the return trip from there is also questionable. Also, it's unclear where I need to place the Grail, which is located in a place where I could have found it a long time ago, but that wouldn't be fair.

Description:
I completely forgot about the ifrits and defeated them at a stage when I had nothing else to do and didn't know where to go next (in the late game). In my opinion, you can defeat them in the late game with a large number of titans and cyclops; it will be an easy victory.
I carried the Grail with me for a long time, wanting to place it either in the Fortress (for magic) or in the Castle (for morale and increasing the number of archangels). In the end, I don't remember anymore; I think I didn't place it anywhere. If we dig up the Grail early, besides the bonus in the citadel and +5,000 gold, it doesn't give us anything, no significant advantages, so you can safely place it in the citadel.
