Incidentally, it has not been named yet so feel free to suggest names.
The deadly Mire Skath is often the last thing venturers into the deepest Swamplands ever see. Only fire seems to keep the Skath at bay, and then only when it comes out at night to feed, or as the Swamplanders are known to say when travelling the deep swamp; 'Never venture far from your campfire at night or the Skath will have you!'.
The horrifying and near-legendary Blackwater Beasts are rare indeed, with many stories surrounding their existence. Some say they destroy settlements in the swamplands if they are not appeased or shown enough respect, others say they were once a proud, intelligent race who angered the Titans and were warped into a hideous monstrosity for their crimes, forever bound to wander the swamps. The truth is far more disturbing- the Blackwater Beast oftens takes it's prey without killing it; to feed live to their young.
Ambushing prey by hiding under the dark waters of the swamp, the Morasskin's muscled body allows it to tense it's considerable frame for a swift, deadly ambush from the waters. Only the long fin that protrudes from the water whilst it swims allows those that travel into the deeper swamps to spot this creature before it's too late. It is said there were once many of these beasts (hence the compound name 'Morasskin' i.e Kin of those that live in the morass) but time and encroachment by the 'civilised' races has severely dwindled their numbers; but this is of little comfort to those that face them!
