Idris (Guide) the surveyor — ranks every legal corner by pips, then mix, scarcity, cove, and room to grow
Pemba Pips first — count the dots on the touching fields; build where the goods flow most
Vera A good mix — three different goods beat the same good three times
Senna The scarce good — seek the island's rarest resource; everyone will trade for it
Rafi Reach a cove — settle where a 2-for-1 or 3-for-1 port turns spares into what you need
Anja Room to grow — leave open neighbours to expand; never box yourself into the coast
