Shrapnel Dragon's map of the Underground Myrmidex key is as follows: 1 - Entrance west of main teleporter area. 2 - Entrance southwest of Kurak Village. 3 - Entrance at Seggalion's hideout. 4 - Entrance east of Drum Hill. 5 - Entrance in spider caves. Q - Xyxxxtl, the Myrmidex Queen. (The Black Moonstone is behind her.)

Blue: Teleporters. The main teleporter area goes NW, N, NE, E, SE, S and SW. It's pretty obvious when you look at it on the map. The others are linked by numbers. Red: Black Staves, Kotl Shields, and The Device. Purple: Generators.
