This winter, artist Steve McNiven and writer Cull Bunn will collaborate for a mysterious new project at Marvel Comics. Titled "MU," the new work will arrive in January -- and that's about all the information we know for sure right now.

However, the bottom right-hand corner of Marvel's teaser image provides another clue: "Find out more September 1st [at] 6:45 pm ET." It is unclear what details will be announced at this time or where fans should expect to learn them.

McNiven's past work includes "Civil War" and "Death of Wolverine." Bunn is best known for "Sixth Gun" and currently writes "Uncanny X-Men."

"MU" arrives January 2017.
