"Maybe wishes can do something wizards can't. All right," she says. "Coins come in five varieties that I know of. I have them named for the number of points in their shape; the higher the number, the more powerful the coin. Four of them are simple - threes, fours, fives, and sixes."
On each word, a dark purple coin appears in her hand, and she sets them out in a row on Lazarus's coffee table - triangle, square, pentagon, hexagon, each with a hole through the centre.
"Sevens are different." She shows Ehail a dark purple seven-pointed star, but vanishes it again without putting it down. "The other kinds of coin are safe to use as far as I can tell, but without special preparation, wishing on a seven can have disastrous consequences. I've heard of things like someone losing the left half of their body, or exploding with enough force to destroy the house they were standing in at the time. I know how to safely use a seven, but because they're the most powerful kind of coin, I try to make sure that as few other people as possible find out."
