Born of the union of a Human and a Merfolk, Mertouched are very rare. They inherit their Human parent's versatility (and adventure-lust), and their Merfolk parent's aquatic traits and playful personality.

Mertouched possess the playful personalities of their Merfolk parents, love pranks, and are rather mischievious. Just like Merfolk, their jokes may be somewhat cruel, but they are not an evil people. In fact, Mertouched are a very loving race indeed to those they accept. They also share their parent's love of the sea. They like to play with aquatic creatures, and relish sunning themselves on rocks with their kind. Jewelry from the sea is held dear, as well. If pushed into battle, Mertouched are capable warriors. They prefer to use weapons of true Merfolk make, such as tridents, spears, nets, crossbows, and harpoons. Sharkskin armor is also used.

Mertouched make good diplomats, going from Merfolk villages to Human coastal towns and ports. They enjoy company of other non-evil aquatic races as well, such as Tritons and Aquatic Elves. Even they are few and far between, Water Genasi also get along with Mertouched. Nature spirits and Fey are intriguing to Mertouched as well. Sahuagin are loathed, and are enemies of the peaceful Merfolk and Mertouched.

In non-Forgotten Realms, Mertouched revere Eadro, who is the deity who created Merfolk and Locathah.

In Forgotten Realms, Mertouched and regular Merfolk worship non-evil deities of the sea. Istishia is common, as well as Eldath and Valkur. While they don't devote themselves to Umberlee, they acknowledge her wrath and power and make payments to temples of her.

Mertouched names are that of both Merfolk and Human variety. Merfolk names are elegant, which use the Aquan language, which bears a slight resemblance to Elven.
