Description
It is not enough to simply keep the Guardians from taking the Fang. We need to get it into our possession. Travel to the Black Garden and claim the Fang of Regulos for the Defiant. Be warned, however, that you will need to hand it over to a companion. It is so tainted with Regulos's power that to hold it for too long can be devastating for one's health.
Upon completion
There is still a touch of the dark on you. I can tell you have done as I asked. How did it feel to hold an artifact of such wonderfully terrible power?
