I know they were produced, but they're quite impossible to find, exactly like the swamp goblin headhunters, heavy spearman, the dwarf scout pack, the blackblood goblin spearman and archers, the firstborn repulsar knight of the order of mallus and the exemplar, and many others. In more than ten years of internet searching I've been able to find a good number of rarityes (such as the devout unholy champion or the shadow stalker, or the elf warrior of the sun), but for a lot uf units, especially if warbands, I had to find something to represent them without having the original ones. But I always tryed to find the correct "look" of the minis.
When it wasn't possible, I modified them. And sometimes the result was ugly, so I had to change or let it go.
One of the must difficult things I've done (almost finished) was the building of the standard bearers of the dwarf units that have never been produced. Recreate the right look was something hard. The result is quite fun, but acceptable. I still have to learn a lot in managing the green stuff.

Anyway, I've probably identified the right dwarves to modify to represent the dragon clan. I'll try, and if they're ok maybe I'll place some picture.
To what I'm allowed to know, all the remaing stuff of the stocks of Chronopia is now in the hands of Prince August, to whom I've already buyed a good number of blisters, but for some units I already mentioned, I think it's quite impossible nowaday to get them. For instance, the stygian desert crawler... I've seen it only once in an auction on ebay, and the price went so high that I couldn't reasonably afford it. A chinese man contacted me once from Singapore, just because I bought every Chronopia auction of the two months before, to ask me if I was interested in buying his army, containing a lot of stygians (including two crawlers!) and firstborns, but I already had the half of what he was selling, and he asked me 500 dollars. The price was reasonable for what he was selling, but, considering the weight and the consequent shipping fare, and the fact that I was interested only to a half of the army, I refused.
That's it. But i can assure that me and my friends are having a lot of fun even with a great number of proxy units, and I think it's a kind of hommage to the game, and not a lack of respect, because what I could buy, I get it. For the rest, I had to solve somehow.
Cheers.
