Narva was the goddess of beer and brewing in Nivorah. Only a few Rider clans maintained her worship after the destruction of the city and through the exodus.
Ride Like the Wind[]
Narva first appears in Ride Like the Wind.
Worship[]
You can only worship Narva if you chose her as the god you took out of Nivorah in clan creation. Even then, you cannot build her a shrine, nor sacrifice to her. However, if you selected Narva, you will always be able to put an extra point of magic in Diplomacy during Sacred Time, regardless of the composition of your clan circle.
On the Circle[]
You cannot have a worshiper of Narva on the circle.
