Kreaven was created by Geoff Johns and Doug Mahnke.
Major Story Arcs
Kreaven was one of the members of the Indigo Tribe who travelled to Oa to recruit the Green Lanterns in helping to defeat the Black Lantern Corps by combining all the lights from the Emotional Spectrum which in turn severs the Black Power Ring's tie to its host.
The Secret of the Indigo Tribe
Kreaven was one of the many Indigo Lanterns on the planet Nok who tried to convert Sinestro into a member of their Tribe, and was also one of the many Indigo Lanterns who chased after Hal Jordan and Sinestro when they were, at one point, freed from their indigo rings.
