Excerpts from the Self-Guided Tour of the World Serpent Informational Center

The hallway is long and walled in tile and steel, but you will notice it does not echo.  The constant rush of saltwater and poison outside is an unending susurrus that swallows sound.  First-time visitors  often feel that the structure is pulsing faintly, the walls breathing with the motion.

This is an illusion.  The visitor's center is not near any of the lungs.

As you walk along, you may feel free to touch the walls or floor and  feel their warmth.  Jormungandr is a reptile and therefore cold-blooded, of course; the heat is the exothermic reaction of the  venom impregnated in its every muscle and bone with the exterior metals and ceramics.  The infrastructure requires constant repair by specialized teams.  Their mining equipment is tipped with diamond and  coated in cat's blood to neutralize the effects.  You need not fear; while collapses were common in the early days, the visitor's center has never suffered any lapses, whether structural or autoimmune in  nature.

The central columns contain the actual grid.  Please do not approach them.  Electricity flows along the grid through Jormungandr's nerves and bloodstream, piping information and power along its length and therefore throughout the world.  The Plague of Quakes in the late 1800s was eventually diagnosed as a degenerative seizure disorder; improved wire shielding and a decades-long corpus callosotomy at Jormungandr's skull in the Marianas Trench, completed in 1973, have resolved these problems.

Your tour will conclude at the door marked in purple.  The gift shop is open year-round.
