Have I missed out? At the beginning of the game I told Newboy not to use the medallion that he found, so he uses armour. I thought that he would stand more chance of surviving the assault if he didn't rely on a medallion he found.

That quest will continue in Ch1 if you accepted the amulet as payment from the reavers.

Hmm well nothing yet in chapter 1. In my quest log it shows the quest is completed in the prologue. I guess I can't do it then.

Do you have the medallion in your inventory ?

If you do you'll have to bring up the medallion subject into the conversation with a specific character in CH1.

yeh I have met the herbalist in the village outisde Flotsam. I can't talk about the medallion so I guess I can't do it.

Yeah, in that case i guess you can't which means you don't have it on you.
