Azure Lagoon

Azure Lagoon belonged to the Second Sea and is tagged both Unobtainable and Removed, so it cannot be visited today. What remains is a record of what it held, and it was a lot: an Angler, an Innkeeper, a Merchant and a Shipwright lived there.

Four of its fish have documented values: one Rare, one Legendary, one Extinct and one Secret. The standout is Verdant Mirage, a Secret averaging C$17,500, far above anything else on the list. Phantom Brine, a Legendary, follows at C$1,282, then Algae Lurker (Rare) at C$357 and Reed Striker (Extinct) at C$356.5.

Notice how little rarity labels predict here: the Extinct fish sells for about the same as the Rare one. Only the Secret breaks away from the pack, by a factor of more than thirteen over the Legendary.

The named species also include Murkfin, Lagoon Dart, Brackscale, Swampjaw, Glimmer Guppy, Azure Prowler, Bloomtail and Depth Drifter, but those carry no documented price.

Verdict: this page is about history and curiosity. If you still own a Verdant Mirage or Phantom Brine, the numbers above suggest keeping the Secret as the one to hold on to.
