pazio or 3rd party?

[Spindoc]

Are the subraces of aasimar and tiefling like angelblooded, and archon blooded part of paizo or 3rd party stuff?

[LazarX]

Yes.

[Veltharis]

They're directly from Paizo. Check out the "Blood of Fiends" and "Blood of Angels" books.

And there's plenty of third party material on both. My personal favorites are the Green Ronin books which should convert into Pathfinder without too much trouble.
