Ins1dr was the user ID of a HoloNet user who was active during the waning years of the Galactic Republic. At some point during the Clone Wars, Ins1dr posted a message on the Cularin holonet node, claiming that the criminal Sot-sirc had recently returned to the Cularin system and that Sot-sirc had previously helped Len Markus to locate the Darkstaff, a powerful Sith artifact.
