The Varisian generator draws primarily from Romanian names.
While there's no mention of Varisian surnames in the Inner Sea World Guide, the Varisian characters in Paizo modules do have them.
When choosing names that start with a letter or letters, keep the prefixes short. One or two letters work best!
Adjusting these settings can help fine-tune your name list, but if you make them too aggressive you might not get any results at all.
