We have one more Sister Seraphim from the old Adepticon 2014 tournament army! This is an out of print figure from the I-Kore VOID range. I don't believe this is part of the Archangel set, however.
As you can see, the wings are done quite differently, with a harsher, more angular design.
The base is the same green marble on which all of the sisters were based. A very fun set to make!
