You didn’t have to read the litRPG series in order to understand Vertigo. This is a self contained story, with only minor references between the two.
Vertigo is a virtual trading card game. But trading card games are completely different inside a virtual world. Here Cas will have to hunt out the creatures she wants to add to her deck, and earn the right to their assistance.
Because this is a side quest I am releasing Vertigo for free a chapter a week. It is available on both Wattpad and RoyalRoad for free. The first chapter is already available. A new chapter will be released by Saturday every week. Bookmark, rate, and review please!
