Aluna has the strongest influence on tides. Its regular, predictable orbit creates a primary tidal cycle with two high and two low tides each day, but these can vary in strength based on its position.
Nalus, the second moon has an eccentric orbit, resulting in irregular effects on the tides. At certain times, Nalus’s influence strengthens or weakens, leading to exceptionally high or low tides when it aligns with Aluna.
Tidal Variations by Phase
Spring Tides
When Aluna and Nalus align (either full or new phase of Aluna), their combined gravitational pull causes extreme high and low tides. This effect is most noticeable along coastlines in areas like the Manura Sea and the Huntdowns Ocean, where tides can rise or fall dramatically.
Neap Tides
When Aluna and Nalus are at right angles, their gravitational forces partially cancel each other, leading to moderate, stable tides. This pattern is common in the Galtawa Sea and Niasano Expanse.
Tidal Regions and Phenomena
Different regions around Caemothas experience unique tidal phenomena due to local geography, currents, and magical influences.
Manura Sea experiences some of the most extreme tidal shifts due to the narrow straits and funneling effect. At spring tides, the water rises rapidly, creating whirlpools near certain coastal inlets. Low tides expose underwater ruins, reefs, and rare resources, which people often harvest cautiously.
Domain of Calberg known for irregular tides due to its magical nature. During a "Tidal Surge" (a period when both moons align at their closest points), the Domain’s tides fluctuate wildly, with water levels rising and falling unpredictably. This is a dangerous time for ships, as currents can change direction in minutes.
Hasslis Waters the many whirlpools here are influenced by both the tides and geothermal activity below the ocean floor. On a high tide, whirlpools intensify, pulling objects to the ocean floor. During a low tide, the water becomes relatively calm, creating a narrow window for safe navigation.
Huntdowns Ocean this area experiences long, shallow tides influenced by strong undercurrents. During low tide, a “Tideway” reveals temporary sandbars and coral reefs that can be crossed by land. However, these areas flood quickly when the tide returns, posing a danger to those who misjudge the timing.
Seasonal Tidal Patterns
In Caemothas, seasonal changes affect tidal cycles, influenced by the positions of the moons and the planet’s orbit.
Monsoon Season (Summer)
During the height of summer, the intense warmth affects the tides, especially around Kiyoage and Boreal. Tides tend to be higher, causing flooding along the coastlines and seasonal “salt tides” that bring nutrient-rich seawater into rivers and coastal marshes, influencing agriculture.
Winter Tides (Winter)
In the colder months, tides tend to be weaker, particularly in the Arctic Abyss. Some coastal areas near Mauvaiscolac even freeze over, trapping ships and isolating islands. Ice floes drift with the tides, creating hazards and natural obstacles for navigation.
Spring High Tides
During the spring equinox, both moons align at their closest approach to Caemothas, creating a period of very high tides across the world. These are celebrated by coastal cultures with "Water’s Reach" festivals, where they honor the sea’s life-giving and destructive powers.
Unique Tidal Events
The “Great Unveiling” in the Niasano Expanse
Every 20 years, Aluna and Nalus align closely with Caemothas, creating an unusually low tide across the Niasano Expanse. This event, called the "Great Unveiling," reveals a submerged land bridge between islands and exposes ancient ruins. It’s a time for exploration but also danger, as creatures from the depths come to the surface.
The Whispering Tides of Kingsgard Ocean
During full moons, the tides around Kingsgard Ocean create strange sounds as water flows through coastal caves and underwater chasms. Local legends say these are the voices of lost sailors, and coastal communities conduct remembrance ceremonies during these tides.
Galtawa Sea’s "Golden Tide"
In early autumn, a phenomenon known as the "Golden Tide" occurs. This rare event brings bioluminescent algae to the surface during low tide, causing the water to glow at night. It’s considered a good omen, and locals often hold celebrations along the shoreline.
Cultural and Practical Impacts of the Tides
Fisheries and Tidal Harvesting
The extreme low tides, especially during spring tides, allow coastal communities to harvest shellfish, seaweed, and rare aquatic plants. Specialized professions, like “Tide Fishers” and “Reef Harvesters,” time their work to the tidal patterns, gathering resources during low tides.
Tidal Calendars and Religion
Many coastal cultures have developed complex tidal calendars to track both moons and plan their activities. Some religions even worship the moons as deities, with festivals and rituals aligning with tidal events. For example, followers of a sea goddess might offer sacrifices during spring tides to ensure safe voyages.
Shipbuilding and Ports
Ports across Caemothas are built with tidal ranges in mind. Some coastal cities, like those near Juraska and Vendamosa, have large dry docks that use low tides to repair and build ships. Floating docks and tethered rafts are common in places with extreme tidal ranges.
Magic and Tidal Influence
Tidal Runes and Charms
Some mages specialize in tidal magic, harnessing the gravitational pull of the moons to amplify their spells. Coastal communities might employ “Tide Mages” to control water levels in fishing areas or provide safe passage through dangerous tides.
Mana Pools and Tide Pools
Along the coasts, tide pools infused with magic during specific alignments of Aluna and Nalus can hold temporary mana wells, amplifying spells cast nearby. These are sought after by alchemists and mages but are only accessible at low tide.
