Stop me if this has been discussed before, I'm super new here and haven't perused too deeply into the forums yet.
I'm just wondering, I was re-reading The Hero of Ages tonight and came across the part where Sazed, in the intro to chapter 49, said "The power in the Well was of Preservation, and an Inquisitor could only have taken it by first removing his Hemalurgic spikes. That, of course, would have killed him." So my question is in two parts. First, why were the inquisitors unable to hold the power while carrying Hemalurgic spikes? Was it because they were too tainted by the power of Ruin to hold the power of Preservation, or was it because the nature of the spikes themselves? If it's the latter reason, why was Vin able to hold the power if the earring from her mother had been blocking her and kept blocking her from the power until it was removed? Why didn't that Hemalurgic spike prevent her from taking and releasing the power at the well?
I haven't read the Bands of Mourning yet, I'm getting to that as soon as my wife catches up to me here soon, so careful with those spoilers if possible
