This page contains Glest tileset files and download links .
Tilesets are selected at the Glest new game setup menu and determine the graphical nature of the world which we play in. Desire a frost-bitten Nordic environment or the scorching sands of sub-Saharan Africa? Tilesets will get you there!
Additional notes: It's basically a Halloween themed tileset, hardly more than remixing resources from the original Forest and Dark Forest tilesets; thus you need to have installed these both.
I tested it only in GAE, but it should work for Megaglest as well. Vanilla Glest won't work because the textures are in PNG format.
