[You guys were not that specific as to what you were doing exactly, but here is sort of a guess. most of you will take the whole round to get all the way there anyway]
The main light suddenly goes on. It is not as bright as it ordinarily is, and the shape of a sprawled human body is projected on the water.
With Murdoch in the lead, you all fly towards the lighthouse. Murdoch blasts one of the shadowy figures with eldritch energy from each hand, shattering two plate glass window/walls and clearing a path for the others to enter. Both hit (64dmg) and the figure falls to the ground, the two wounds in his back still emitting low flames. Alethia fires three arrows, glowing with holy energy and burning with fire, through another window, all striking one of the men and badly wounding him (51dmg).
You all can now see the scene inside. The lighting machinery remains open, with eight more men that you can see standing around it. All are wearing polar bear pelts turned into human-shaped clothing, which include a hood made of the bear's faces coming down over their foreheads. All wear clawed bracers with the holy symbol of Auril, an evil goddess of storms, on the backs of their hands.
Aleena is lying on the lens of the light, bleeding rapidly from two long slashes on the inside of her forearms. As the blood spreads on the lens, the image projected into the sea turns red.
