I'm planning on using 60mm plastic figures where possible, 54mm (1/32nd scale) otherwise. I haven't gotten rid of my smaller scale force either so maybe at some point I'll use them as well.
For the Tharkallan Empire I've decided on Expeditionary Force (XForce) 60mm figures:
http://www.expeditionaryforce.com.sg/catalogue-c-9.htmlIn addition to the Early Imperial Roman range [i.e. Tharkallan Empire], they make Celtic Barbarians, Early Germans, Classical Greece, Ancient Macedonians and Ancient Persians.
They also have a range of Hundred Years War French and English.
Their future plans include Punic Wars, Ancient Egypt and Biblical Era, IIRC.
For immediate Enemies and Allies(?) of the Tharkallan Empire the western "Celtic" tribes are covered: Kost, Celtos, Teleos, Soleos, Brithos, Erin, and, possibly, Slontos. I will try and give them some sort of tribal identity. I don't mean collecting an army for each, but finding some way to swap them, either standards, or shields, or having detachable figures that can be switched around on the bases to make the unit look more like one tribe than the other.
The Early Germans will work as Wenelian barbarians, and also Toonolian Marsh tribes.
If XForce does come out with Ancient Spanish, then I will use them for Shem and Zingara.
Imther (and my Dunlendings) will be Ancient Thracians (part of the XForce Macedonian line).
For Amazons I am planning on using LOD figures which are also 60mm. Oronin, Oraya and Ologog comprise the Amazon Confederacy.
https://lodtoysoldiers.com/They have a War of Troy range which also includes Greeks and Trojans.
The XForce Classical Greeks will supply: Ilmoria, Vilmir, Lormyr and Holay. Perhaps Sylila, but it just occurred to me that a non-Confederacy Amazon nation might be a good idea. Some Macedonians might find there way in as well.
Kos, Kroy, Ossary and Corlay will use LOD Greeks and Trojans.
Dara Happa, Saird and Turan will be a mix of Ancient Persians and Macedonians. Dara Happa being more Persian and Turan more Macedonian.
Deelguy and Eyagi are desert tribes, but otherwise I know nothing about them. The Hyrkanian Steppes and the Redlands have horse nomads. Erigia and Pent are still a bit nebulous as are the further Eastern nations, except Pan Tang, which I am intending to be very Chaotic, with Samurai as warriors, and many demons and monsters of various sorts.
The Shield Lands, comprising Furyondy, Jemmerdy, Valon, Olokand, Ulek and Vanch, I am planning on using the XForce Medieval range. I think the character of the nations becomes more "Rus" as one goes eastward. Vanch is a frontier nation, mostly wilderness. The conflicts there will be small scale, between local Marcher Barons and the Forest Tribes.
Dol Amroth will also use Medieval figures. They are Swan Knights per Tolkien, but are NOT Elves or Half-elves*. I have already sourced the helmets that I think will work with the XFoce knights. They are my version of the Knights of St. John, only I am not using Christianity or Islam as religions. For religions I am doing something else. A blend of Glorantha and other sources. So, Humakt as premier War God.
* I don't want to use Elves and Dwarves, nor Orcs. At least not, the Tolkien, or D&D or GW versions. Trolls, along the line of Gloranthan Trolls, and half-trolls, like the Tusk Riders I like. I'm working on Tusk Rider conversions right now. I have some mounts, and am just waiting on suitable rider figures (in transit.) Sprites as found in the Thane Tostig saga, definitely, and Evil Dwarves as suggested in the Narnia stories, maybe. Beastmen, yes. Giants, yes. In Lohwand they are about 6" tall.
Shazar, Tarkesh, Haradwaith, Calormen and Carmania are the Turks. But they are not Islamic. They probably all worship a pantheon headed by Tash - see "A Horse and His Boy" by C.S. Lewis.
Umbar are a mix of Carthage and Corsairs, ala Tolkien.
Haida Pakala are also pirates or corsairs of even more irregular appearance.
The Chakan Forest area is veing populated by Chintoys Aztecs, Mayans and Incans.
Stygia is Ancient Egypt, of course. I have some figures for them from an old manufacturer and they are part of XForce's plans. The rest are a bit more muddled, and subject to change.
