Domains: Island navigation, the archipelago held in mind as one known thing, the channels between islands that have their own water, their own tides, their own behavior.
Era of ascension: Great Expansion (~3,100 BSD). Cohort: current. Aneryxika rose with the Ansari gnome enclaves' consolidation through the Pelican Isles, when the channel-navigation knowledge that had been held in family-pilot lineages for generations was acknowledged by the enclaves as a worship rather than a craft.
Worshipped by: Ansari channel-pilots (the trained navigators whose knowledge of the Pelican Isles archipelago is held as a single integrated map of currents, depths, and shoals), the small-boat fishers who work the inter-island runs, the harbor-elders who keep the tide-tables specific to each island's lee. Ansari does not share Aneryxika with the open-water polities; the channel-knowledge is doctrinally specific to the archipelago. (The worships edge is authored downstream on the worshipper, not here.)
Aneryxika is the daemon of the between-water, and her domain is the water Gavelos does not properly know. Gavelos is the open-sea god, the merchant-route god, the deep-water navigator's patron whose prayers cover the long passage between distant ports. The water between two islands in the same archipelago is not Gavelos's water. It is a different kind of water, shallower, faster, full of currents the islands themselves push and pull through their lee shores, with depths and shoals that change between two seasons and that no chart compiled from open-sea reckoning will capture. The Pelican Isles fisher who is taking a boat from one island to the next prays to Aneryxika for the channel, not to Gavelos; Gavelos is prayed to only when the fisher is leaving the archipelago, which is a different journey.
The channel-pilot's worship is the channel-knowledge itself. An Ansari pilot does not navigate by chart; the channel-knowledge is held in the pilot's memory, taught from a senior pilot over years, and includes details that no static chart could hold: the way one channel runs different at three different stages of the moon, the way a particular shoal moves a quarter mile across two seasons of an unusual winter, the way the wind off one island's high ground will steer a boat off-course in the lee of the next island unless the pilot corrects for it. Aneryxika is held by the Ansari to be the daemon who preserves the chain through which the knowledge is taught across the generations, rather than the daemon who teaches it directly.
The lore-handle Ansari channel-pilots carry is: "the sea between two islands is not the same sea as the sea around one." The doctrinal corollary is that a navigator who has approached the archipelago from the open water and who believes they know how to move within it has misunderstood the water they have just entered. Ansari pilots will hire out as guides to outsider vessels through the channels; the fee is high and the doctrine treats the fee as a courtesy to the daemon, not to the pilot. A pilot who is undercharging is held to be devaluing the worship as well as the work, and the harbor-elders will counsel them quietly.
