This is the basic map of New Troy, explained in brief in this post. Those readers following these posts will remember that this is an area 15x10 miles, with the hexes 1 mile in size.
Entering one of the gates, marked on this map by a star, takes you to Faerie, which has the following map. Here, the hexes are 6 miles in size.
The geographical features here are fundamentally the same, but at the same time, different. They are, in essence, a looking glass version of those in New Troy - except in every respect more dangerous, more unusual, more vibrant, just more.
Four things have changed. The settlements have been renamed as 'Shees' and are Faerie 'kingdoms'. Thripsey Shee is so named as a tribute to its namesake in the Lyonesse books; Trinovant Shee is a play on 'New Troy'.
The caves in the North East of the area, which on the mundane New Troy map are the gate to Muspel, in Faerie are the home of the dvergar - much more akin to the Dökkálfar of old Germanic/Norse myth than D&D "dwarves".
I'm going to start keying in the hexes for New Troy and Faerie in coming posts.
