Recording a note about this group for posterity. I used to be part of the game circa 2002-2004 (roughly).
They met monthly in the downstairs of Solid Rock Cafe, I think on a Thursday. I remember drinking upstairs, talking about random unrelated stuff, waiting on them to open downstairs so we could properly 'get into character'. I was a member of the Tremere for a while before I became it's leader for a short time before I stopped going.
Part of the way through playing, I hosted a home event (on Sat 22nd Feb 2003) where we had the prince of the city, at the time, in attendance. There are some pictures in my gallery at https://gallery.mckillop.org/index.php?/category/404 A friend from Scotlug, Caroline, was also part of the LARP. She's in the photos. You can see from the gallery, we didn't dress up exactly (though some people wore pretty goth outfits in the pub), but we had some props related to the current storyline on that particular evening.
The group still continues on Facebook, with some familiar faces, almost 20 years on (https://www.facebook.com/groups/gvlarp/)
