Searching for the Rune Sphere (remake)

Yes, I haven't seen something like this in a long time. The author clearly overdid it with the dwarves. The constant generation of dwarf heroes with a rather substantial army is definitely an overabundance. Did I understand correctly that I should ignore them and aim for the blue tent and the Dungeon? After playing the second campaign for about six months, I easily repelled their attacks (destroying the catapult first), and the leader generally charged forward with almost no losses. By the way, my hero reached level 27 (the limit) somewhere around the 4th month of the game. I don't know, maybe I'll still finish it, or maybe not (my enthusiasm has waned).

I barely managed to deal with the dwarves, took the harness, and captured the axe (is that not too much security?). And where can I find the Rune of Flames? Everything seems so complicated in this map.
