Male Viera names?

[APitaPie]

Stated clearly where?

We have so little Viera canon lore to go on.

The Viis NPCs give you quite a bit of lore, and while yes, they aren't Viera, the cultures of the races in The Source and The First have pretty much the same base fundamentals. While their cultures are slightly different between shards, their ways of life and biology are the same.
Now as for quotable lore I could link here, like I said, its late and I have no desire to go digging at this exact moment.
