Starting from scratch, the absolute best site to learn more about the World of Tekumel is
Tekumel.com.
This site has it all: background, history, links, downloads! It can be a bit over-whelming at first and easy to get lost - there is just so much cool STUFF!
I would start with the section called
"The Eye of Illuminating Glory" and after reading that page, follow the link to the
"Lands of Tekumel." From here you can gather an overview of the nations on Tekumel - the Five Empires, the lesser kingdoms and tribal entities and the non-human realms.
Of particular interest are the two comparative maps, one of which shows Tsolyanu, the
Empire of the Petal Throne, with an overlay of Europe, and the other which shows this hemisphere of
Tekumel with an overlay of Asia.
In the first comparative map Yan Kor is barely shown, being off the map to the north beyond the Desert of Sighs. The initial area of operations in the current war between Yan Kor and Tsolyanu - and the starting point for our range of miniatures - is in the area of little Pijena in the north-western corner of Tsolyanu. Pijena is essentially a Yan Koryani puppet-state. Before the war the border ran north of that mountainous range in southern Pijena: the Atkolel Heights. Now the Yan Koryani occupy the heights and the two nations face each other off on either flank of this mountain bastion.
This is the situation where our Range begins - in the role-playing game events have progressed several years beyond this point: the war has ended, and Tsolyanu has been embroiled in a bitter civil war. All that you can read about in
History section.
