Well...Shifting gears from the character art.... Most of us know of the mention of the " House of Hades" on page 317 of the Last Olympian. Obviously it refers to the family unit of Hades and not the actual temple, but with the video of Uncle Rick talking about how hard it is to be Hades or a son/daughter of Hades, I think it is safe to assume that the title refers to the family unit of Hades as well as the temple in Epirus.
