Thanks for the info! I have the Dreadnaught already from TTK, but still missing the other two lithos.
For the first series, I got the House of Devils and Heroes Rise, missing the Summoning Pit.
Edit: Got the Dark Court at Ebay! \o/
Bold ones are missing:
Destiny: House of Devils / Heroes Rise /
Summoning Pit
Taken King: Dreadnaught / Dark Court /
Third?
