Old topic of male Viera.

[LineageRazor]

In one of the sidequests, you actually indirectly encounter a "Watcher", implied to be a male Viis. You find the slain corpse of a monster you're hunting, perforated with arrows. When you return to the village, a Watcher is theorized to have done the deed.

Much like males on the First, male Viis leave their village and live isolated lives, it seems. How they learned that you were "allies of the Ronkans" if they remain isolated is unclear... I suppose they were watching!

As for there being "not enough space" bear in mind that this is a MMO, and the scale for everything is very hard to judge, in order to prevent enjoyment from being impacted by having to walk miles to get anywhere. The Greatwood is far, FAR larger than what we see. There's likely much more than a two minute walk between the various villages. There's probably more villages than what we see, or the ones we do are far, far larger, with hundreds of residents, rather than less than twenty.
