Character and Player Parameters
Many commands take optional character and player options.
character: Which of your characters to use. Without it, Inconnu picks the one that fits, or shows a menu to choose from.player: Usually admin-only. Lets admins view, roll as, or change another player's character.
Automatic Character Filtering
Without a character, Inconnu narrows your characters by context. If you have a mortal and a vampire, /bol uses the vampire, since mortals can't Blush. If only one character has a Necromancy Trait, rolling Necromancy uses that one.
