// A magic wand standing diagonally on a small round velvet cushion of deep purple with gold tassels: a slim dark wood wand with a spiral-carved handle, a gold band, and a bright glowing five-point star tip in yellow-gold, with three tiny sparkles around the star. Make it chunky enough to read: the wand is at least 2 blocks thick and the star big.
