Inland
England (or what's left of it). See also Outland.
Though Riddley's map only shows a small area, the general geography is consistent with a rise in sea level that ought to leave a good deal of the rest of Britain intact, and Riddley writes on the map that he doesn't have room for the whole of Inland. The characters just don't seem interested in what might lie beyond their own region; perhaps a lack of curiosity as a consequence of their cultural downer on "clevverness"? RG
Kent has long had the sobriquet "Invicta" (unconquered), so you could also see Inland as a contraction of "Invicta-land". It also recalls Orlando's line in As You Like It: "...the thorny point/Of bare distress hath ta'en from me the show/Of smooth civility: yet am I inland bred/And know some nurture." MJ
