Proposed Canon

The geography of Erfworld is divided into a hexagonal grid.^Erf-b1-p046a Each hex has an associated x,y coordinate.^Erf-b1-p010 Units are not permitted to cross hex boundaries except when on Turn^Erf-b1-p115; however, units are able to move freely within a hex, and move objects, such as notes, across the hex borders.

Hexes are further divided in to square-sets^LIAB_Text_45. How many squares are in a hex is as yet unknown.

For more information on hexes and how they are used, see Movement.

Known Locations

• X: -1214 Y: 455 Where Jillian croaked a Twoll and three uncroaked en route to Gobwin Knob. ^Erf-b1-p010
• X: -1218 Y: 467 Where the Archons met Ansom's forces. This may be the same hex where Sir Webinar and Dora met Jillian after her release from Gobwin Knob. ^Erf-b1-p042
