"Dehbed Asavara Parthian horse archers?" Topic

Continuing our tour of the Mortal Realms before we plough right into Godbeasts, we are taking a trip to the Realm of Fire where a Verminlord Corruptor has run up against the Seraphon in his bid to locate a valuable ingredient to one of the Thirteen Great Plagues…

The Story So Far
Verminlord Corruptor Sepskrik arrived in the Realm of Fire with a definite purpose in mind – he was travelling to Serpentis, the City of Secrets, to locate an artefact known as the Serpentstone. With this, he would be able to finally unleash the Undulant Scourge, one of the Thirteen Great Plagues. However, he needed help to locate it within the ruined city and so he mustered the forces of half a dozen Clans Pestilens.

Hundreds of Plague Monks scouring a ruined city for so potent an artefact was never going to escape attention though, and Slann Starmaster X'loc X'hul duly arrived, ready to confront the Verminlord and put an end to his search…

Just bought "L'art de la Guerre" and while looking through the army lists I see that Parthians can field Medium cav horse archers, much like Sassanids.

Now doing a little digging and I find Dehbed Asavara, apparently Lesser noble cavalry, armoured horse archers who could also carry a spear on unarmoured horses!
Dug out my Maa Rome's enemies 3 and on the front cover is the same figure, in the plates he's called a 1cAD cataphract.

As I already have enough Cataphracts and Light horse archers painted up to field a Parthian army for LADG, I can now kitbash some MC from my spare figures.

Can anyone point me to any historical pages for a bit more info on these troops?
