Dungeons & Dragons Classics, Volume 1

I would venture to guess that this was the beginning of the D&D comics of old, because Agrivar's and Kyriani's origin stories begin here. I've already read the other set of Classics with Agrivar in it. Funnily enough, it doesn't explain why Agrivar only appeared in the first story arc - there are two story arcs in this volume.

This comic series certainly did not age well at all. The first story arc tells how the party of five wound up together. Their names are... somewhat cringe-worthy in this day and age, but probably very awesome back when I was a kid. It tells of their first adventure together, being guided along and protected by Selune (whose depiction and origin story was completely at odds with the 2nd and 3rd editions that I'm more familiar with) to recover an artifact belonging to her and defeating an old enemy of hers.

The second story arc is where Agrivar just goes off on his own (and none of his former teammates even mentions him). It features another quite over-the-top and completely-ignoring-mechanics kind of adventure centered around the Musicians guild and jesters (of all things!) in Waterdeep.

You can get a kick of nostalgia of how D&D was back in the first edition, but if you're looking for superb storytelling or great characterisation, you won't really find it here.
