The Slithering is a new Pathfinder adventure that's going to be released later this month. As an accompanying piece to it, they've released a document with some pre-generated PCs that you can use if you decide to take on this creepy, crawly adventure. You can download these new characters for free now.
From the article:
Inside The Slithering Pregens document, you’ll find Melvok, a kobold witch; Oraka, an orc investigator; Savshin Starwatcher, a lizardfolk oracle; and Zathri, a catfolk swashbuckler. Why yes, now that you mention it, we did take this opportunity to give you a sneak peek at not only four new ancestries set to come out in the Pathfinder Advanced Player’s Guide at the end of the month, but also the four classes making their Pathfinder Second Edition debut in the same book! So whether or not you’re planning on playing, running, or completely ignoring The Slithering (I don’t recommend that last one, by the way), you won’t want to miss out on this free PDF download.
