The "Ineffables" collection is inspired by an angel who runs a bookstore (represented by the flaming sword that tends to "lose") and a demon with sunglasses who sometimes let some sibilants slip through (represented by a snake coiled to an apple). They may sound familiar to you ...

You can combine the pieces from this collection with those from the "Damiel" and "Dragon Wings" collections, depending on whether you like feathered wings or membranous ones more.
