Sigil

In the CrossGen universe, Sigil (2001–2003) follows a young soldier who, after an encounter with an alien artifact, is marked with a mysterious sigil that grants him immense power—and makes him a target in a galaxy-spanning conflict. Written primarily by Mark Waid and Barbara Kesel, with art by Ben Lai, Paul Pelletier, and Scot Eaton, this four-issue series is a key entry in CrossGen's interconnected Sigilverse, blending space opera with personal stakes. It matters as a foundational piece of the publisher's ambitious shared universe, introducing a core concept of superhuman potential tied to cosmic mystery.
