New riddle

I haven’t seen this one before. Any ideas from the hivemind?

In wagons they came,
in chariots they fought.
Stirred by Sauron they were not really to blame,
but destruction is what they sought and were taught.


I tried “Wainriders” and “The Wainriders”. No effect.

My first hunch was Easterlings

Anyone figure this one out yet?

Well, it’s not Balchoth.

Any other bright ideas?

It should be Wainriders, but could be Easterlings, or possibly Variags. Balchoth could have been an option as well. If not that, then possibly a broken riddle or someone typo’d the answer into the computer, or maybe split the word into Wain Riders.
