This takes the form of a blank white card. It appears to be whatever document the bearer claims it to be when they show or otherwise present it to someone. The resemblance isn’t perfect – the DC to see through it is 13 + the bearer’s proficiency bonus.

The card itself is an embodiment of fairy glamour, so this effect is neutralized any time the card touches cold iron (prolonged contact may cause the card to evaporate away, like the fading memories of a dream). The effect otherwise lasts as long as the card is observed
