Tag Greenly and Bink Otauna. You can’t talk about one without the other. The seminal Rosencrantz and Guildenstern of the EU, both were born as low level force sensitives(which is explained as a mistake brought on by Darth Plagueis’ manipulation of midi-chlorians) they were accepted into the Jedi order. They had a direct effect in many of the events of the mainstream continuity and interacted with basically every main character of the two trilogies.
They were in the background for most of these confrontations and had the convenience of always being in the wrong at the wrong time (depending on who you ask). They eventually met their ultimate fate on second Death Star.
