A fisherman from Cassardis. He lost his brother in the dragon's attack on the village.
A fisherman of Cassardis, he survives the initial attack by the Dragon unharmed, (Harbinger of Destruction); and resumes his normal life with the rest of the village. He is "friends" with Valmiro, and grows concerned for him when Valmiro goes on his expeditions.
At the start of Harbinger of Destruction, you see the Dragon immolate an NPC who looks just like Merin from behind, this could be Merin's brother Cortese, who was mentioned killed by the Dragon's attack.
