They couldn't provide an answer on the "Wait for Me" show.

Hello everyone! I've resorted to extreme measures and decided to create a thread here. I apologize in advance if I'm in the wrong forum section. Unfortunately, the forum is very old, and the interface is not intuitively clear. Now, to the point (Spoiler, help me find the hero of the "Fortress" faction, also known as the swamp faction). Back in 2003, I played Heroes of Might and Magic, both versions 3 and 3.5 (but without the customizable Wog options). When I didn't have access to a computer, I went to a gaming club to play. Unfortunately, I don't remember if it was version 3 or 3.5, but in addition to the main campaigns, there were extra missions on random maps in the Campaign section. I started one of these and began the game. The character looked like a very fluffy white dog (a gnoll). The map started in a swamp area, without a castle. I had to find a castle within 7 days. At the beginning, the map was almost divided in half by a river. In general, please help me find this hero, and ideally, the campaign. I'll immediately mention that before creating this thread, I searched all over Yandex and Google, watched all the videos on the first pages, read all the descriptions of castles and rare heroes. I looked at all the Hero/Faction/Castle tables. I learned a lot of new things, but I couldn't find what I was looking for. Once again, the hero's avatar was a snow-white dog face, more like a husky, with green eyes. More than 20 years have passed, unfortunately, that's all I remember. P.S. The hero's face didn't look like a custom-made one by an amateur. The style was exactly the same as the canonical characters, a fluffy white face with green eyes.
