The Illuminerdy has a nice post up called The Worm Latitudes, in which Nanouk synthesizes the Lambton Worm, European eels and the Sargasso Sea into a pleasing mix to add into your campaign, should it be running short on limbless squick. (Seriously, watch out for the lamprey photos. I hate those things.)
The Lambton Worm is a fine example of a Dragon or Wyrm or Sea Serpent that you can include in your game, and even features a built in tactic for slaying the beast at the climax.
And a death curse. Wow.
Who doesn’t love a death curse?
Click through for the full story of the Lambton Worm and how it might fit into your campaign. I’m currently trying to figure out to hook it into the Elder Worm mythos of the HERO universe. Two threads about immortal worms have to tie together eventually.
