While I don't know about any potential "Horror" links to the Item form bottled demon; I ran in it years and years ago with one of my mages.
It sucked out a point of magic and made me make it "My Preicous". lol.
My whole team had to take me down and get it from me. At the time we ran it I wasn't aware of the SR/ED link because I hadn't bought/played ED and didnt want to. I later bought the module but just stuck it in "The Archive" cause Im not a GM.
So, I cannot comment on what Links
That one had,.....Buuuut you might wanna look at this next paragraph a little closer.
2009 Shadowrun Tournament
Idol Threats
Twenty years ago it gained the attention of two dragons, now it wants your attention. This years Gen Con tournament revels in Shadowruns twenty year history, while it manages to pack all new surprises into the mix. All teams advance, so plan on playing in both sessions on both Friday and Saturday Night.
I read that descrip when I was getting ready for Gencon that year and just Knew they were referencing BD. Turns out I was right. And yes there is a link in there. But I'm not gonna say more until I know it's cool, they wanted it kept under wraps if i remember correctly.
