Deverelli · The Isles · the treacherous isle of merchants

Deverelli

The isle that will sell you anything — silk, safe passage, secrets — as long as you can pay, and doesn't pretend otherwise.

The wealthiest of the Isles, across the Arctile Ocean from everything Violet knew — and the one place still trading with Navarre, where her father's trail goes cold in a book merchant's hands.

The merchants' isle

Neutral means for sale — nothing personal.

Deverelli doesn't pick sides; it prices them. It'll trade you near-transparent silk or a stranger's secret with equal indifference, worship no god but the ledger, and stay the last isle still on speaking terms with Navarre. Treacherous isn't an insult here. It's a business model.

Asher's trail

The archive beyond the Archives.

Whatever Markham scrubbed from Basgiath, Asher's research ends up here — left with the merchant Narelle Anselm, waiting years for a daughter who'd follow it across an ocean. Violet comes looking for an ally and finds her father instead, in the one place his knowledge could survive being erased at home.

The File

Region
The southernmost of the Isles — a neutral merchant kingdom across the Arctile Ocean, twelve hours south of Cordyn by dragon or two days by ship.
What it is
Tropical and rich: white beaches, turquoise water, soft green hills, and a capital, Matyas, tucked beneath one enormous tree canopy.
Who holds it
King Courtlyn IV. No gods, no war — science, alchemy and commerce, in that order.
The trade
Famous for near-transparent silk, and for selling information to anyone with the right price. Loyal to the deal, not to you.
What happened here
Following Asher's research, Violet's expedition comes seeking an ally — and the merchant Narelle Anselm, who holds what her father left behind.
Status
The last of the Isles still in contact with Navarre. Courtlyn brokers access and safe routes through the Isles — for the right bargaining pieces.
