Board Game Arena

I just played a game that had a noble available that I've never seen before and isn't in the standard game pack--it required 3 blacks, 3 greens, and 3 blues. What to make of this?

This noble came from the expansion The Silk Road that was release today on BGA
As it doesn’t impact gameplay we decided to add it here wether you are using the expansion or not.
Have a great day
