Trent Di Renna asked about info on Malkionism. For a different (though
generally compatible) viewpoint, pick up the source Nick forgot to mention:
Codex #2 (list price $4.00 U.S., available from Wizard's Attic and possibly
other sources). It contains a History of Fronelan Malkionism, a Fronelan
Timeline, Galastar: A City Reborn, Tribes of Mortasor, Galastar's Myths,
and other info on Fronela and Glorantha generally.
Also useful: The University of Sog City Conference Guide, a LARP handbook
from Reaching Moon MegaCorp.
