You can't play as theocracies

Is it possible to play the prophet Velen?

No, unless you unland him, give feudal castle, switch to him or use cheats.

I know they spawn around the year 610 but how to star playing them?

You can play as Velen's feudal vassals though.

And What about Nerubia which i believe is this square on the up left site of map? Is it will be something you will work on the ck2 version or something you will do when you move on ck3?

It won't be in CK3 and in CK2. We decided it will too buggy and hard to implement so we scrapped it.

Shame about Nerubia. I think the Warhammer "Geheimnisnacht" mod handled the Under Empire, which is similar, in a decent way.

They connected a province in the smaller map to corresponding provinces on the greater world map, and then just gave both provinces increased movement speed between them. Still took months to get troops from one province to the other though, but it worked. Could have done something similar with just one province in Silent-Reach leading down into Nerubia.
