There are a number of unstated duties that attach to the role of Primarch's Equerry. Precisely what those duties are depends heavily on the actual Primarch of course. In the case of Kharn, Captain of the 8th Company of the World Eaters Legion, one of them was teaching his Primarch some degree of tact and diplomacy.
"Sister!" Angron called out as he escorted his companion into the Imperial Palace. Courtiers scattered prudently out of the way as the towering figure charged brutally across the mile-wide corridor to sweep up the princess in a bone-crushing hug. Kharn nodded approvingly and quietly called in a medical team for two ambassadors who hadn't quite been fast enough and were now suffering from broken bones. This was a substantial reduction in the usual casualties.
Angron hesitated for a moment, wracking his mind for what came next. "Are you well?" he asked.
"I've very well, Angron," Serenity assured him and kissed his cheek. "How are you."
"I've..." He remembered her polite but excruciating lecture the last time he told her about his skull collection. "I've brought our brother Corax to meet you."
Serenity's eyes flickered to the dark-haired giant who was looking around the palace, pretending not to be impressed. "That's very sweet of you Angron."
The primarch lowered his voice so that the basso rumble could only be heard by everyone in this wing of the Palace. "He was a prison bitch," he confided in a sincere attempt to be discreet.
Kharn removed his helmet and started hitting his face against the nearest wall as Corax glowered and Serenity blushed.
