I wrote a short preview of the upcoming Pathfinder Comics: City of Secrets #1. Without spoiling anything, all I'll say is that fans of the Dawn of the Scarlet Sun module (Free RPG Day 2012) will be in for a treat.
Pathfinder Comics: City of Secrets #1 Preview
I'm assuming the change in numbering is simply a way to entice new readers to jump on, as the issue is definitely a great entry point to the series. You get a brief mention of the goblins, Lamashtu, and Blackfang to catch readers up on what's happening. I was worried that it was going to be a completely standalone new story, and while it is the start of a new story arc, it's nice to see that it is very much in continuity.
