The Nine Keys

Zariel's ninth key is not a key at all -- it is nine witness-marks, one laid on each city's wonder. Visit nine of the wonders and press your mark to each: the Reeflight, the Thorned Standard, the Great Anvil, the Windbell, the Old Drydock, the Frozen Vigil, the Pyre Memorial, the Elder Bough, the Smuggler's Toll. {n}/{req} marks set.
