Walls LOS versus flyers

[Hoongming]

Hi, either someone has posted this before and the search was unable to pinpoint it or it was clear to everyone else. So the question is do walls block LOS from flying creatures aswell ie can I make my archers fire over walls by giving them eagle wings?

The first is covered thoroughly in the rulebook, but the answer is no. Therefore the second answer is yes, but it is also possible to give archers the indirect trait to fire over walls with LOS blocked.
