Distance, Magic and Movement
The map of Nycos is based on 49-mile hex spaces, each hex representing seven internal sub-hexes seven miles across. The term’s origin derives from mystical histories and claims of magical abilities among the various races and species that inhabit the planet.
Generally this is accepted, though the particular mathematics are not internalized, as people think in squares, rather than hexes in most situations (we know length and width, not hexagonal geometry) The standard unit of measure between locations on the surface of Nycos, regardless of the hexagonal distances are called Farspells. A Farspell generally equates in Terran Terms to 10 miles, or roughly 50,000 feet. This happens to equate approximately to the maximum distance a Line of Sight Spell can be cast across a treeless plane, and the maximum range of any Mortal Spellcaster’s effects. For most purposes, a hex therefore is approximated as five Farspells across for travel purposes, and seven farspells across for navigation on the map.
Colloquially, A Farspell is halved and quartered, as it were, in describing how to navigate.
"Go down this road half a Farspell, and you reach the turnpike. Once you get there, go another quarter down the port-wise path, and you'll see the Sanguine Citadel on the right, and a very nice Winterhaven pub cross-ways at the top of a hill. You can't miss it."
