OOC: We do....but not in places that will get us killed, and not in ways that randomly have us appearing just in time to be a convenient plot device for the Holis. Not to mention the Laminari are a 'hidden' people, they do the vast majority of their existence, and work cultivating, traveling, etc, in secret.
Most people only know of them as a lost empire "The Ancients" (The Melodari), and in recent times, those who have survived Zyomanari attacks, know of the Zyomanari. Rather few races know of the existence of the Laminari themselves. The Holis know...but they only knew The Melodari, and a single Laminari Caravan, that has long since been elsewhere, and is probably rather far away from where you are.
Most Laminari Caravans hide in Nebulae...but so do alot of Monstrosities...So pretty much its a safe bet that trying to find the Laminari without our wanting to be found is like playing dice with closed doors, and both sides hold a tiger....one of them is just capable of being nice, the other is insane.
We travel yes, we are many yes....but we are secrets, legends, whispers, myth, in the eyes of those who have not met us face-to-face, and even then, it is select and few.
