Hey, I've been playing Skyrim for about 10 hours or so now (total playtime I mean, not all at once ) and I've made my guy an archer.

Thing is the bows I've been using aren't that great, I think I have one now that does about 10 damage per shot.

I was wondering where I can get a decent bow?

(I realise this sounds like a stupid question but I literally have no idea )

You'll find one eventually.
I started iwth an Imperial bow with a frost enchantment.

Also, I love the power behind the bows now. Sneak shots put an enemy down with one arrow.
