From publisher blurb:
AN ADVENTURE FOR Odysseys & Overlords
SUITABLE FOR 4-6 CHARACTERS OF 4TH – 5TH LEVEL
Rostrum Point, an island at the head of the straits of Mandibar, is home to a strange ruin, the last remnant of a fortress built in times long past, when gods fought and died for the love of mortals. Due to its structure – a central tower, with two ruined bastions on its flanks – the ruin has been named “The Giant’s Throne” by sailors. Once, it was home to a fearsome weapon, a “Heat Ray ‘’ which could target any ship or company for thousands of feet around and ignite it within seconds. The delicate mechanism has succumbed to time’s march, and even were it whole, its operation is beyond the ken of contemporary folk.
Despite sitting in Madrean waters, Rostrum Point was claimed by Estria decades ago. Rather than fight for an otherwise desolate rock, the two nations have agreed to treat it as a symbol of unity, watching the major shipping lane between them. However, with the meddling of a sinister third party, the garrison has gone rogue, re-assembling the ancient Heat Ray in a reckless attempt to hold the trade route to ransom. The adventurers have been hired to help resolve the situation.
