From the introduction: This collection of kludges is to facilitate the few characters still in play that have access to Traveller style Psionic Talents but who have been migrated out of their starting campaigns. There may also be one or two cases where characters who were not from a Traveller campaign have learned to use PSI Talents. The use of PSI Talents comes in two parts: the character’s Psionic Strength Rating (PSR), and the Psionic Talent groups the character can use.
