Potion

Ageing Potion
An Ageing Potion is a potion which causes the drinker to become older. The ageing only takes place in the body and not the mind. The more of the potion that is drunk, the larger the aging which occurs. The effects of this potion are temporary.

An Ageing Potion is also resistable by an Age Line, so people who have taken the potion still can't cross the age line if they couldn't before they took the potion.
