ISRA, the Interplanetary School of Research and Advancement, is one of eight Psi Orders in the Trinity era. As with the other psi orders, ISRA was founded in 2103 by one of the eight proxies — in this case, Proxy Otha Herzog. Members of ISRA are often referred to as clairsentients (after their Aptitude), seers (due to their ability to see into the future), clears (slang for clairsentient), or eyes (for their ability to see the unseen).
