I just reread Immortal and it said that Darroc's torque and armbands are black, JB's torque if I remember is black and silver and Adams are gold. I am wondering if maybe the Seelie the light fae wear gold thus light and the Unseelie wear black or black and silver thus dark. I don't know just a dumb thought there. And as was brought up before in Into the dreaming the Unseelie King has been missing for about 30 years which to me seems fishy.
