Browsing through Sebastian Giacobino's facebook page (the guy who made the art on Mablung, Haldir, new Legolas, Erkenbrand, etc) I found this spectacular piece of artwork commisioned by FFG, as of yet unknown and unreleased. According to him, the piece (and, presumably, the card it will be on) is called "Revealed in Wrath", which makes me think that it will be one of our new Noldor themed cards in the new cycle, most likely Spirit or Leadership event. I will also add that this is one of my favorites pieces of art in this game ever, owing to my assertion in the art-themed episode of COTR (I wrote that last email) that the art is only getting better and better.
Apologies to FFG for posting it here in the forums (considering that they have taken down all the pieces of artwork that have "leaked" before the its card is released). Just take it as my personal revenge for giving us nothing in the past weeks in terms of previews and releases.
So, without further adue, here's the piece in question, and let the speculation begin!
