As well as being advisors on the Guardians of the Galaxy film, which is due for release on the 1st of August, Dan Abnett and Andy Lanning have produced the tie in comic to the film. The comic was released today in stores as well as the Marvel app.
From the comic, we learn Taneleer Tivan aka The Collector (Benecio Del Toro) is located in Knowhere. Comic readers would know that Knowhere is situated in a dead, severed, celestial head. And was the Guardians base of operations.
Ophelia Lovibond is indeed playing Carina (as seen in Thor: The Dark World), The Collector's daughter.
The Orb is located in a temple on Morag, which has been underwater until now for the past 300 years.
Ronan is after the Orb. And will do bad guy stuff with it.
Gamora used to be loyal to Ronan but now works against him to obtain the Orb for The Collector.
