La cittadella

A strange structure appears at the border of the solar system. Its origin is a mystery, its origin unknown... Nathan Never and the android Link, sent to investigate, will find themselves face to face with a life form that’ll force them to make radical choices and confront with their different kind of humanity...

In the cartoon on page 25 we see a reliquary containing a Colt 1851 Navy, or [censored] Zagor's colt!
