The Detect Magic Rune is the first rune quest in Shadow Quest.
It is used to detect where powerful magic has been used."Search the Kingdom for Crystals, that shine bright and true,
one of each color: red, green, yellow, white, and blue.
Venture forth to Mana Falls in the forest by noon,
and the shield in the city, asleep under the moon.
Then journey on to Pixie's Hall where you will find two,
next to the owl in Tangled Woods when you are through."
