|David A Hargrave (May 25, 1946 – August 29, 1988)|
Given that this is clearly a genie wish fulfilment scenario I'll skip the obvious (like Matt Mercer, Ginny Di or Stefan Pokorny) as I don't watch much "streamed" gaming and am not a fan of the current Dungeons & Dragons background canon and look way, way back to the "Dream Weaver" himself, David A Hargrave.
Back in the day, when I was first discovering the joys of Dungeons & Dragons, David was running - and writing up - his own Arduin campaign, which began as a major houseruling of the original game before becoming its own entity (after TSR's lawyers got involved, as I understand it).
Of all the campaigns, especially the original half-dozen or so that are widely known about, the biggest influence on me, and my ideas about gaming, was Dave's Arduin, particularly the original trilogy of digest-sized booklets he published in the late '70s.
It's why it's probably the most namechecked of the early campaigns - along with Dave Arneson's Blackmoor - on HeroPress.
Just click on the Arduin tab below and scroll through the many mentions of this inspirational game.
From everything I've read about Arduin, Bloody Arduin, and all the interviews I've read with Dave, this is the game I would have loved to have been a part of.
