A new faction is burning its wings to get to your tabletops in Aeronautica Imperialis. It's the Necrons. And... I guess they don't use wings, but they are making their way to your tabletops soon.
From the announcement:
The skies of Aeronautica Imperialis are busier than ever, following the release of Wrath of Angels, which introduced the Adeptus Astartes and Asuryani into the game for the first time. Now, an ancient race awakens to claim the area of engagement for themselves.
