Guild Wars 2

I was thinking about this when in a water quest about an elite skill for the Norn where they could shape-shift into a shark

or a whale, a dolphin or some other air breathing water going creature.

There are a variety of animals out there that just have to have animal spirits. Maybe some forgotten or some never even heard of before.

I think this would conflict with the lore of the shape-shifting skills themselves. The Norn do not transform into just random animals. They take the shape of the four prominent spirits of the wild: bear, raven, snow leopard, and wolf.

I’m not 100% on this, but I believe it is because those are the only spirits of the wild still powerful enough that their blessing can cause the transformation. Also, I’ve never heard mention of a spirit of the shark (though it could possibly exist).
