The first hand comes from Lore (the Hired Hand node). The other two come from notices on the board later on: the fishmonger from the mainland wants 40 halibut, and the harbour café wants 65 monkfish (that one opens after A Selkie's Favour in Lore). Both are caught out Beyond the Light. That's clearly too hidden though, so I'll make it clearer in the game. Thanks for playing!
