Hiyas!

I was wondering what ship is that depicted on the Citadel of Skulls adventure cover?

Thanks!

I don't know about the big temple-y bit in the background (which could be a section of ship, I suppose), but the flier in the foreground looks to be a Valkyrie gunship, or a variant thereof. Pure airbreather (so not something you could launch from and recover with a starship, unless said starship entered the atmosphere and flew down to the Valkyrie's service ceiling (13000m)), can carry roughly a squad of troops.

I'd imagine that it is the actual Citadel of Skulls depicted on the cover along with a Valkyrie.

At a guess it is meant to be a Valkyrie Skytalon, as that particullar "pick heavy thing up and put it down again" variant of a Valkyrie is statted up in the module.
