SOLVED. Fantasy trilogy about land surrounded by mist and shadow monsters

[Reader]

Hello please help me find the name of the series. I believe it was trilogy and details are sketchy. I believe it was a British author due to the spelling of words like “colour”. The main city was tierd and had a giant greenhouse or smokehouse where meat was cured which had an almost addictive taste. The beasts that were cured could be found wild and traveled to the end of the world which was hidden by mists. The hero had to navigate a swampland to find it where he eventually found himself in another world. The hero was also pursued by a villain who I believe was a shadow figure. He created minions who persued the hero. I also believe the book was an older book.

Thank you for your help. I’ll try to promote details as I remember.

After weeks of wracking my brain and trying to think of details of this book…the name finally hit me as I was drifting off to sleep. Glitterspike hall by Mike Jefferies. Thank you and enjoy.
