@Wyvern , @Calibre This happens because of an extra blank line in the OnOpenMacro for the template. If you look at the command line after opening the map, but before doing anything else, it asks for a symbol catalog. This is obviously a bug with the style, I'll notify @Ralf so he can fix it.

Unless Ralf beats me to it, I can do that.

Bring up one of the Schely trees for editing from the Symbol Manager, and then use Tools -> Distance to measure the height of it.

Now, edit your own symbol, and just scale it up so the height matches.

Note that your symbols should be edited in the source symbol catalog where you have them, if you edit the symbol from within a map where you have used it, only the copy stored locally in the map will be changed. Also, when you change it in the actual symbol catalog, be aware that maps that already use the original smaller version will continue to use it (because symbol definitions are copied from the catalog into the map on first use) unless you first purge it from the map.

Very nice. Nothing can beat a touch of certain death :)

Maybe the Dungeon Worlds annual can be a good start?

Won't help you build crystal cities (not sure about resources for that), but it is a nice way of mapping an Underdark-like world.
