The religion believes in reincarnation, but that you will be reborn in the past. People of today are those re-born of tomorrow, with some discarded as trash. The most pure will be eventually reborn in the mythical paradise-like past, where people lived for hundreds, or maybe even thousands of years.
This goes nicely with beliefs into foresight (you know a little about the future because you have been there), but also to many complaints of how things are going always from bad to worse.
Finally got the idea for an orcish currency:
A cold-hammered piece of raw iron, resembling some kind of a dagger. The Dagger is easy to carry, hard to forge, may be used as a crude weapon in case of emergency AND the iron being a valuable resource... may be used directly for weapon-making. May be carried openly on the belt of a mighty Orc. A new insult: 'to beat someone with someones money' . Self-explanatory.
The Forest of Throck:
Throck forest is divided into three parts: a region of twisted black magic, which is dark and hemmed in with the legions of sable pine. This is Spindel, and is occupied by the hideous Ettercaps and their spider-pets. The second area is the chaotic elfin-wood, where the druids work their wyrd magic amongst the oaks. The last part is Udnalor, the home of the gnomes. Finding themselves surrounded by these chaotic forces they dwell as quietly as possible beneath the surface. Their culture is a fascinating one to visit, and in the next few miscellaneous ideas, I shall examine the ways and customs of THE GNOMES OF UDNALOR, with a view to role-playing them.
