Having read the Tallarn book one aspect really confused me.
At one point a fleet named the golden fleet, arrives led by a rogue trader named Sangrea mistress of the Eagle Claw. The fleet is stated as being made up of mercenaries with 300 ultramarine warriors also on board.
The fleet is only discussed in a couple of paragraphs. It flies into Tallarns system telling the iron warriors it is on there side, then destroys the iron warrior ships nearby before heading towards the planet. Where, it destroys everything imperial and traitor in the atmosphere trying to support the ground forces. Then the fleet leaves the system.
This seemed a random and almost pointless addition to the story and almost like it was lazy writing designed to create a way the loyalists can gain the upper hand.
Has this Golden fleet ever been mentioned or talked about before in books, source material, rules etc? Or is this the first time they have ever appeared? Is there any explanation given for there random act at Tallarn where they seem to decide not to pick a side?
