Anoxic bogs are most often found in northwestern Europe. What makes these bogs special is their lack of oxygen- thus “anoxic-“ and their content of chemicals called tannins. When living creatures happen to fall into a bog, their tissue is preserved because tannins keep it static and all the little mites that cause decomposition can’t live without oxygen. (Bones, however, are often dissolved if the peat is too acidic.) Not only are bodies preserved, but clothing and trinkets as well. This is how big bodies are made! You might have heard of the Tollund Man or the Yde Girl, both famous examples of European mummies, from Denmark and the Netherlands respectively. These mummies can be preserved for thousands of years.
This is the Tollund Man, probably the most famous bog body
Now, marshes and bogs aren’t exactly the same thing, but for the prevalence of marshland in Mossflower country I’m sure that some of that could be a peat bog.
Slegg, Dirig, Gruntan Kurdly, the victims of the wytes… countless named and unnamed woodlanders have found themselves sinking in the swamp. Countless bodies under the surface.
I recently discussed in this post that “the 22 [Redwall] books cover hundreds and hundreds of seasons, their stories spreading farther than memory can reach.”
That is all to say, imagine what tales are hidden inside Mossflower wood. Imagine what relics of long-gone eras are preserved in the bodies of those who wandered through Mossflower and found themselves an unfortunate end. Imagine (accounting for the fact that not all muggy water is a bog) what the Maudie, Barbowla, and Log-a-Log Luglug were blissfully unaware of when running from the Brownrats. Just one of the thousands of stories Redwall has to tell.
