History 

The personatus are immortals thanks to their high level technology ; they can't die with naturals way. They spend, thousands and thousands year ago, all their time to make Death like an old memory. But this immortality created, throug the ages, a powerfull fear of death, wich become a kind of religion ; the religion of Death, of the End. Their only fear. When you spend thousands years and even more to build something, the fear of losing life become a paranoia. That's why  they are macabre, dark, and even their ships are like grave-worlds.

They have a natural disposition for mental manipulation, and they use it to force others people for agrements-for a certain time, always in order to avoïd their own end.  But it's not free...Personatus are the first, and the only race, to be Mercenaries Diplomats. 

Some said they are the best diplomat thanks to their schools where citizen spend thousands years to learn how to negociate ; others said it's due to their mental disposition. In fact, they use Dust and mental power to force treaty.
