 * Plugin Name:         Avandra (Project Zero Plugin)
 * Plugin URI:          https://github.com/{USER-NAME}/{REPO-NAME}/
 * Description:         A blank plugin developed for budding WordPress plugin developers. You can use this as a starting point for all of your plugins. The plugin goes under the name of "Avandra", after the Changebringer deity from Dungeons and Dragons.  She has been used in the liveplay stream Critical Role and is the Goddess of freedom, adventure, and luck.  Since plugins allow you the freedom to build your WordPress site as you see fit, it seems like she would be the best deity to name this plugin after.
