Did I bug out the Sentry quest? Witcher 1

So, I'm playing W1 for the first time, and I'm on chapter 2 and I have 9/10 of those Sephirah things. I've got the dude who I need to accuse to go to the Mage Tower but now I just need the last Sephirah to finish this shit up.

According to online sources, I have to do the quest The Sentry but I can't get it to start. Supposedly I need to get a Lightning Rod from either the Dwarves or the Order. The Order guys won't sell to me, but the Dwarves will, but they don't offer the q item to me. I looked online and see that Kalkstein is supposed to trigger this somehow but he's not giving me a lot to talk about, tried everything.

Any suggestions?

EDIT: 3 hours of running around I figure it out 10 minutes after I ask for help. For future Googler's reference, talk to Vaska in the swamp.
