Kalabel Nautomantic Apparatus

The Kalabel Nautomantic Apparatus is a derrick-like structure off the coast of Port Talon. It was designed by Morrow of the Kalabel Chantry to confine the leviathan sea creature positioned below it, and provide access to both the creature and the coral that surrounds it.

Location
The Apparatus is in the sea, within sight of Port Talon. From the harbor, the Apparatus is visible about halfway to the horizon.

Appearance
The apparatus is a spire approximately 240 feet tall, formed by four steel beams which create a slender pyramid shape. Inside the beams is open space, save for several square platforms made of steel grate that are placed at intervals along the length of the spire.

Platforms
Each platform is marked with arcane runes and has railings around the edges for safety. A zigzagging set of stairs connects the platforms from top to bottom. Each platform also has a large circular disc in the center which is transparent, such that an individual standing on one such disc could look up or down and see through -- either to the sea beneath one's feet, or up to where the large steel beams meet.

Prisms
Hovering at the top of the derrick are two sources of light: stacked octagonal prisms that emit brilliant light (purple and green, respectively). In its resting phase, this light is strong enough to penetrate the waves beneath the derrick, illuminating the sea in the area, and making the rest of the sea beyond darker by comparison.

Activation
The Apparatus is activated by magical means. Several low-level spellcasters may work together and speak a united chant to begin an activation.

When an activation begins, the light of the two prisms strengthens and focuses along the central axis of the structure. The light takes on a more actively magical quality, displacing the water below and providing a clear view of the sea floor, and the leviathan on it. Some quality of this light acts to confine the leviathan by physically pushing it to the sea floor.
