This category lists the core Evergreen champions (unlocked for all new players).
The Champions may be automatically added to the category by the Champion’s Infobox (via the Evergreen parameter, when set to "core") or by manually adding them to this category at the end of the Champion’s page (the latter case is probably a safer way given the potential impact of the Infobox’s parameter use for some conditional code related to Elminster Patron, etc.).
