Rupus Dyne was an experienced soldier, and an inveterate womaniser.
Dyne was counterpart to the Shard Kulik Molcomb, prior to Molcomb's death. The two of them had an affable working relationship which was slightly marred by Molcomb's unspoken lack of respect for counterparts. Both of them knew that Molcomb would be happier on his own, but neither of them ever brought it up as an issue.
Dyne's weapon of choice is a pair of heavily customised Moachim P15 Autolock Pistols.
Dyne was enjoying himself in a brothel on Low Cerin when Molcomb was attacked by Maber Castigon (→SFTD).
About a week later, Dyne was cleared of negligence with respect to Molcomb's assassination, when he was able to show communication logs which recorded the many occasions on which Molcomb had elected to carry out his business without Dyne present.
Dyne was temporarily assigned to Elm Caden, who was not at all impressed by that arrangement and eventually dumped Dyne in favour of Bruiser. While he was still acting as counterpart to Caden, Dyne took part in the ground element of Operation Keystone (→TRD).
