There was a tradition for when the Imperial family gathered in any great numbers. It had started with just the Emperor, Serenity and Horus and after centuries it had become an institution that simply could not be avoided (despite efforts by certain Primarchs and Senshi after Angron was recovered and they were exposed to his 'singing'): Music Night.
And so, on this particular evening, with more than half of the Primarchs gathered with their sister and several of her bodyguard at the Emperor's field headquarters, Serenity sang. Horus played the piano. Sanguinius demonstrated heartbreaking skill on the flute. Fulgrim produced a violin to accompany a duet by two of the Senshi. Even Mortarion had grudgingly produced the double bass and scratched out a tune in a competent fashion.
The Emperor dipped his hand inside a bowl filled with tokens and drew the next person's turn. (By longstanding custom it was random order). "Angron," he announced, frowning slightly in disappointment.
Dozens of flinches were concealed with varying degrees of effectiveness. Dorn nudged Corax (who was lurking between the Primarchs of the Ultramarines and Imperial Fists). "Why don't you look bothered?"
"I won a bet with Angron last week," Corax replied coolly. "His forfeit is not to sing for the next month."
Dorn's expression relaxed. "I may hug you."
"Don't let your cousin rub off on you."
Guilleman leant forwards. "I believe this would be a suitable moment to..." He hesitated and held up his fist. "'Fistbump'?"
The other two Primarchs stared at him. "CoughNerdCough," Corax observed.
Guilleman apparently missed the insult. "That would be a no?"
The conversation halted as Angron stepped up to the stage carrying something that sent alarm through the family.
"Is that...?"
"Oh no." The Raven Guard Primarch shrank into his chair.
"Corax, I'm going to kill you."
"BECAUSE OF CERTAIN CIRCUMSTANCES, I CANNOT SING TONIGHT!" Angron announced. "FORTUNATELY I HAVE BEEN LEARNING TO PLAY THE BAGPIPES."
