Are there any good aligned cold / winter related monsters?

[Yqatuba]

I can't think of any off hand.

[WagnerSika]

Silver dragon

[Yqatuba]

Oh ok good one.

[Daw]

I can't think of any more, but there was a fantasy story called Cold Mercy that might give you a viewpoint shift that you might be able to use. I will try to dig up more information on it without being a spoiler.

[Yqatuba]

I think there should be an agathion based on some cold weather animal. A seal maybe?

[Daw]

Isn't there an Orca based Agathion? Now that you mention it. Away from easy resource ATM, my connection is currently too horribly slow for research.

[WagnerSika]

Cetaceal agathion but I don't really see it as cold based.

[pocsaclypse]

I went through the bestiary spreadsheet on d20pfsrd and the only good aligned creature that had a cold subtype that wasnt a silver dragon seems to be the third party Mimi

[LordKailas]

It's worth noting there are humanoid races like Norns and Adlets which are listed in the bestiary as being neutral. Same as dwarves, elves and humans.

so, you could easily have good aligned versions of these creatures.
