Meeting in Muzgob

Hello, dear players! I have a question – I played a map called "Meeting in Muzgob" a long time ago. But it wasn't the standard one (level 1) – it also had a dungeon. The entrance to the dungeon was on the central island. Below the entrance, a path began – a test for your hero. Each cell had an event – in the first cell, you were attacked by 10k creatures of level 1, in the second, 10k of level 2, and so on, up to level 7 creatures. Further, throughout the dungeon, there were 7-9 heroes (they were initially there) with AMAZING armies – 30-40k creatures of level 7. You have to kill them all to gain access to the last hero. And only by killing him do you win the map.

So – I REALLY want to find this map... I've searched everywhere – there's no information about it anywhere (( Maybe someone can help me?

Thank you all in advance!
