As I mentioned earlier Varka a section of Messagetae are referred as a group of people in persian texts.They are said to be born of a union of man and lady wolf(mythology varka ancestor is said to be protected by she wolf and fed on her milk).What is interesting in Sanskrit also Virka/Varka stands for she wolf. Buddha Parkash too mentioned their origin from wolf.
Taking this Varika/virka seems a clan name of King . Replace it with Virka the guild alderman and reference becomes Great great King Vishnuvarhana the Guildman elder.
