Stormania (2015)

From publisher blurb:

150 leagues north of Mirkasa (near the mythical lands of Jakabol) lies Stormania, one of the world’s northernmost islands. Through some quirk of magic and geography, the island is prone to frequent and extended eclipses. During the long, dark months, all manner of monsters freely roam the land; the locals have learned to keep their doors bolted and pray for a fast sunrise.

Though dangerous, many adventurers have travelled here hoping to uncover the island’s secrets. It’s said the island’s former lord, a giant-sorceror cursed by his own people, discovered the key to eternal life here.

Perhaps your party will be the first to delve into these catacombs of antiquity and return victorious. But you’d best be sure you’ve got plenty of torches first…
