Go ahead.
The RPG::Event is actually a sub-class within the RPG module. Whenever you create an event, pressing Ok creates and stores your event automatically in the MapXXX.rxdata file.
When you load a map, the RPG::Event(s) are immeditately stored into the Game_Event class under the instance @event. Game_Event uses the same methods as player in the Game_Character class which controls movement and such. Sprite_Character uses as an instance these settings to display them on the map on the spriteset.
Just a little FYI because I feel like it.
