Here are my thoughts about this story arc.
Hell and High Water 42-47
This story arc ran for six issues, published from August 2014 to March 2015. Here are my impressions:
The first issue of this arc presents a good deal of exposition—important, but one could become impatient for advancing the storyline.
We get to see the King of Secrets! He and his servants make a striking impression.
Shards of the King's mirror could make for useful relics, given that they connect to similar items carried by Knights of Solomon in the field.
“The Six seeded messengers into each new world.” That is interesting, especially when combined with the different forms that the Six have assumed in various worlds.
At the end of Issue 43 we see someone standing behind Kalfu. I don't recall if I guessed who that was when I read that issue for the first time, but we eventually learn that it is Gord Cantrell, who struck a deal with that crossroads demon.
The appearance of Kirby in his changed form is intriguing. For one thing, it confirms that the snakemen are made from existing humans, which could be a good plot hook. Secondly, it opens the possibility that someone could undergo the transformation process, and yet still retain a semblance of their true identity.
Finally, we see a lengthy battle that sprawls throughout a small town. This could make for an exciting encounter in an RPG session, using a town such as Fort Griffin as the backdrop.
Oh—riding the Thunderbirds into battle is awesome!
