“Who the First Lantern is and what his role will be in the upcoming Green Lantern universe will come into play very, very quickly,” hinted GREEN LANTERN writer Geoff Johns. “The being inside has been imprisoned there for a long, long time. The Guardians consider him their greatest threat, but also their greatest source of power. Whether he’s friend or foe will be up for debate, but regardless he is one of the potentially most dangerous beings in existence.”
“In GREEN LANTERN ANNUAL #1, readers got their first glimpse at the First Lantern, someone who’s been locked away for a very long time—for a VERY good reason!” teased editor Matt Idelson. “His presence in this story is the catalyst for something very bad, and yet his story is only going to grow from here.” via The Source
