As the artist on The Flash: Rebirth, Ethan Van Sciver has his hands full this summer, redefining the Flash universe with his frequent collaborator, writer Geoff Johns.

The project is the second “Rebirth” effort from the two creators, having previously resurrected Hal Jordan in Green Lantern: Rebirth. And it was that “rebirth” that also gave new birth to the ideas now spinning toward Blackest Night, the DC’s headline summer event.

Starting with Green Lantern: Rebirth, readers first saw the concept that fear was behind the “yellow impurity” that had hindered Green Lanterns for years. Then that idea led to the creation of a much broader concept – that emotions have energy that can be harnessed, and the energy of those emotions is represented by colors besides just green and yellow.

That idea became the driving force behind the 2007 Green Lantern storyline, Sinestro Corps War, which culminated with a prophesy that is now coming true.

In this second part of our two-part interview with Van Sciver, we talk more about his contribution to the concepts and visuals that are now coming into play in the Green Lantern universe. While we talked to Van Sciver Thursday about the symbols he created for the corps in the War of Light, today we get into a little more detail about the costumes, characters and weapons of the lanterns that are dominating the stories on the road to Blackest Night.
