RPG 2 – The demons are coming!!!

[Off-topic]For now, all the warnings are more like reminders for the future. Regarding the teleport, she's not the weakest sorceress, but she clearly doesn't have enough power for such teleports (as far as I understand, the mage cities are in the south, and the battle with the demons was near the dwarf cities in the north...). I'm also partly to blame for not warning about the teleport... Well, you teleported in the right direction...[/Off-topic]
Meanwhile, the lights were getting closer and closer... now the translucent silhouettes of specters hovering over the dead swamp of the Heresh Valley could be seen. Nearby, the swamp gurgled dully... What are you doing?

Carefully choosing my path, trying not to step into the boggy areas, I continue to move towards the city...

After some time, I approached the city walls, narrowly avoiding collisions with skeletons, of which there are many here - necromancers are usually skilled in this. But my cloak reliably concealed me... I also slipped into the city unnoticed, taking advantage of the inattention of a couple of Liches who were letting a crowd of Zombies through the gate... Ugh, what a smell!!! Yes, maybe it was a mistake, and I shouldn't have come here? I could have just calmly gone towards the Silver Cities, as I intended... but no!!! (I mentally scold myself). But then my attention is drawn to a small group of skeletons, dragging a strange chest under the leadership of a vampire. And there is clearly something valuable in it - I just feel it!!! I decide to get closer - maybe I can find out something....

P.S. (again, off-topic) I'm just confused with the game's geography... Maybe someone can draw a simple map so that I can at least roughly orient myself? I don't remember if such a map has already been made or not... If so, please provide a link ;)
