darth venamis was a bith dark lord of the sith who served as darth tenebrous' secret apprentice, as it was a violation of the rule of two. after tenebrous was killed by his other apprentice, darth plaguies, he eventually found and defeated venamis, before capturing him and using him as a test subject for his midi-chlorians experiments over the years. after decades of torture and being killed and then brought back to life over and over again, plaugies finally allowed venamis to die, having served his purpose. however, he later revived again in the presence of his new apprentice, darth sidious, until venamis' organs finally ceased to function, and he died for the final time.
