The Risen Isle

 is a shipwreck treasure hunt introduced in Total War: Warhammer II.

Text
The mists part to reveal and island uncharted by even the Great Mapwright. High spars of rock jut from the ocean, like spikes in a trap - a trap that has ensnared some prey. A wrecked ship lies impaled on the small island's coastline; its crew seem to have moved into the interior along with any valuables that may have been onboard. Your ship wisely drops anchor far offshore before the crew make landfall in search of treasure.
