Ymmos was a relatively normal Noble. Serving under queen Mevunnu, he was a respected and powerful man. Mevunnu once took Ymmos with her to show him something. Curious he followed her: It was a lab full of queen larvae and geonosians of all shapes and sizes frozen in time in a vat of bacta. She told him: I have recognised our vulnerable mating situation and thus made this if someone ever sterilises us we can survive it. So if this ever happens i want you to go into this lab and initiate the defence systems then scout out the world to check when we can emerge. I hope you never have to do this but I trust you the most. Ymmos lived on for a few years serving his Queen when in 7BBY disaster struck. The empire betrayed them! It was an aerial gas... everywhere geonosians fell out of the sky and started choking Ymmos immediately knew what to do and quickly ran to the lab coming across his queen Mevunnu who just nodded and whispered: Run. For our glory. He ran into the lab and closed it and turned on the defense system with the best droids they had to offer. Ymmos oversaw this process and took air samples and after being there for a few years he came out 2BBY and left the lab and the planet with his ship and went around the world checking the state of the empire and looking for enemies against the empire.
