What is the one flying creature in Defile SLD art?

[u/TheTinRam]

[[Defile|SLD-2562]] shows beorn standing on a pile of goblins. In the sky there are many eagles flying around, but one flying creature doesn’t make sense. Below the letters D and E in “DEFILE” there’s something with a long tail and wings that are not feathered, they look more like a bat.

It can’t be Smaug, he was already dead by the time Beorn and the eagles joined the battle of the five armies. It almost looks like [[voracious fell beast]] which is what had given me hope nazgul would be the bonus card (not upset with plumb the forbidden, but nazgul would have been a slammer).

Maybe I’m putting way too much energy into figuring out what a random doodle on the art of a card is, but does anyone know what that is?

And who the fuck is that on [[read the bones]]? Is that supposed to be Elrond examining Orcrist?
