To create an NPC called Mr Peppermint:
<<set $mrpeppermint to {}>>
To set his name, age and preferred hair colour:
<<set $mrpeppermint.name to "Mr Peppermint",
$mrpeppermint.age to "126",
$mrpeppermint.preferredHair to "blonde">>
In the story, to ask Mr Peppermint if he likes the PC's hair:
You ask $mrpeppermint.name if he likes your hair.
<<if $playerHair == $mrpeppermint.preferredHair>>
"It's your loveliest feature," he beams.
<<else>>
He shakes his head sadly.
