"Other sons fight the Horse, even though-" her voice dropped to a frightened hush- "the Gill Man came to take away their manhood with the Coat of Stars!"
Any confusion on the part of the Sisters was answered by the painting of the Gill Man, a large, scaly monster dressed in a starry coat with scissors on the end. Or rather, it was answered by the fact that the scales on his chest were blue and displayed the Ultramarines symbol.
"Yes," whispered Sister Rosalind, "this story was definately told by the Salamanders."
The feral worlder moved on to the next series of paintings, each with a symbol that suggested a different Primarch.
"The Great Green One," she said reverently. "Knew the secrets of Fire and Steel. Refused to let the Gill-Man take his manhood."
Sister Rosalind surpressed a giggle, deciding that the next time she saw the Salamanders she would call them Great Green Ones. They'd kill her for it, but it would be worth it.
"The Angel," came the feral worlder's voice, pointing at the next painting. "Emp-Rar's beautiful daughter." Indeed, the golden-haired woman in the painting was remarkeably beautiful, her body barely covered by a sheer peice of cloth, her blue eyes large and sad as she wept tears of blood.
"Was there a female Primarch?" Sister Ophelia hissed excitedly. "I never learned about her!"
"Don't ask," replied Sister Helena. With any luck, the Blood Angels would never end up visiting this planet.
