Darouen Rileau is a fantastically rich Gallente mining magnate popularly known as 'Diamond King' for his well-known interests in precious stone mining – even though he made his trillions in the hyper-lucrative rare-earth extraction industry. Rileau's wealth and deep connections with the Gallente Federation's military-industrial complex allowed him to make his son Luecin's wish to become the Gallente ambassador to the Caldari State come true.
Ambassador Luecin Rileau made for a surprisingly competent occupant of a notoriously tricky diplomatic billet but he had one vice above all others: gambling. Some even said that Luecin sought the posting to the State because of his taste for games of chance. Ambassador Rileau frequented the famous Grand Tiegjon Casino in Vellaine on a regular basis and developed a liking for Pettokori, a popular electro-board game. It was during a Pettorkori session that Guristas leaders Fatal and the Rabbit struck.
Engineering a situation that allowed them to kidnap the hapless Luecin, the pirate lords spirited the Diamond King's son away and put him up for a ransom in diamonds truly worthy of a king. Darouen Rileau was no doubt vexed by his son's foolishness but the ransom was paid in the end and the notoriety and fame of the Guristas leaders increased to legendary heights.
