Castle Alexandr stands on a promontory overlooking the channel between Bonnetaz and the Strymün Isles—a fortress of dark stone utterly unlike the salt-and-bone architecture of its Kuzagt neighbors. The castle predates Kuzagt settlement by centuries, possibly millennia.
History
No records survive to explain who built Castle Alexandr or why. The architecture suggests human construction—the proportions are wrong for elves—but no human civilization in the region's known history possessed the engineering skill evident in its construction. The walls are fitted stone blocks, each weighing tons, joined without mortar in a technique that modern builders cannot replicate.
The name itself is a mystery. "Alexandr" appears in no Kuzagt genealogy, no Ethadian chronicle, no surviving document from any regional power. The castle simply is, and has been, for as long as anyone can remember.
The Kuzagt occupied the castle briefly after establishing Bonnetaz, intending to use it as a watchtower and naval base. They abandoned it within a decade. The official explanation cites "strategic considerations." The unofficial explanation—shared only among council members—involves incidents the Kuzagt refuse to describe.
Current State
The castle stands empty but not ruined. Its walls remain intact, its towers upright, its gates functional. This is peculiar. Abandoned structures in the salt environment should corrode and crumble. Castle Alexandr does not.
Visitors report that the interior is spotlessly clean—no dust, no debris, no signs of animal habitation. Furniture remains in place, preserved as if the occupants stepped out moments ago. Food left in the kitchens does not rot. Water in the cisterns remains fresh.
The castle does not welcome extended stays. Those who attempt to sleep within its walls experience dreams of drowning, of darkness, of something vast and patient waiting beneath the sea. Most leave by morning. Some leave immediately. A few do not leave at all.
Strategic Position
Despite its unsettling nature, Castle Alexandr's position makes it valuable. The promontory commands the main shipping channel between the Gindrik Sea and the approach to Bonnetaz. Any power controlling the castle could effectively blockade Kuzagt trade.
The Kuzagt solve this problem by ensuring no one controls it. They patrol the waters nearby, discourage explorers, and spread stories emphasizing the castle's dangers. These stories are not exaggerated.
Periodically, ambitious captains or desperate refugees attempt to claim Castle Alexandr as a base of operations. The Kuzagt do not interfere. They simply wait. Within weeks—sometimes days—the new occupants are gone.
What Lies Beneath
The castle's cellars extend downward farther than the promontory's geology should allow. Explorers who have descended report passages that seem to continue indefinitely, opening into chambers of increasing size. The deepest reached—according to a Kuzagt expedition whose survivors refused to discuss their findings—contained seawater despite lying hundreds of feet below sea level.
Something lives in the depths. Or something sleeps there. Or something waits. The Kuzagt have sealed the cellar entrance with salt, bone, and old magic, and they check those seals regularly.
The castle remains standing. The seals remain intact. The Kuzagt consider this sufficient.
