The Adventure-Friendly setting is the twenty-eighth installment of the main-series threads from Character Development Thread. It is not specifically based around any particular genre and is open to characters from any type of story.
As the name suggests, it's set in an unnamed area that is a mixture of several terrain types filled with old ruins, caves, dungeons, temples and other staples of the Adventuring genres.
The Apocalypse happened - some time ago, at least a Class 1 and no more than Class 2 - leaving a ruined and ravaged landscape littered with the remnants of ancient technologies and magic. In the midst of the destruction, people are starting anew. A town has grown in the midst of the chaos and destruction - a symbol of hope and prosperity.
The thread can be found here. It started in February of 2018 and is ongoing as of 2019.
