Pleasure World — This world provides delights either rare or impermissible elsewhere. Matchless local beauty, stunningly gengineered natives, a wide variety of local drugs, carnal pleasures unacceptable on other worlds, or some other rare delight is readily available here. Most worlds are fully aware of the value of their offerings, and the prices they demand can be in credits or in less tangible recompense.
Preceptor Archive — The Preceptors of the Great Archive were a pre-Silence organization devoted to ensuring the dissemination of human culture, history, and basic technology to frontier worlds that risked losing this information during the human expansion. Most frontier planets had an Archive where natives could learn useful technical skills in addition to human history and art. Those Archives that managed to survive the Silence now strive to send their missionaries of knowledge to new worlds in need of their lore.
