Benji immediately crinkled his nose and tried to kill off the urge to gag. The sharp stink barely lasted half a second... but it made him think of a wild animal's guts being charred in a flame.

"That... is a Power Pearl," Tyco answered in a flat, measured tone... "It can be charged with a single spell... to be released upon a trigger determined at its creation."
