Heldannic Territories
A nation of the Known World. The southern part first appeared in X1 (1981). The name was inherited from Moldvay and Schick’s Known World (c. 1976). The rest first appeared in X11 (1986). Name changed to Heldannic Territories in Wrath of the Immortals (1992). Never fully developed in official products, although the Heldannic Knights featured prominently in The Voyage of the Princess Ark (1990-1992). Later developed by Bruce Heard on the MML (1998). First fully mapped by Geoff Gander (1998). Later saw many different fan developments.
