Question:
Why is one of your members using the name Atreides as an inRP character? I am absolutely sure that the name "Atreides" refers to the one and only:
"House Atreides is a fictional noble family from the Dune universe created by Frank Herbert. One of the Great Houses of the feudal interstellar empire known as the Imperium, its members play a role in every novel in the series." (And in the games) - Wikipedia
He even uses the first names of some major characters in the universe like Leto Atreides; Leto I was the Duke of House Atreides and Leto II was a God Emperor.
