Merlinus

Merlinus ​is a playable character that appears frequently in Fire Emblem: The Binding Blade and Fire Emblem: The Blazing Blade. He resides in either a tent, carriage, or wagon, with only the latter two being able to move. He must be protected, as he has no means of fighting. As a merchant, Merlinus holds the player's armory optionally during each battle. He is one of the few non-main characters that cannot die along with others such as: Marcus, Nils, Ninian, Oswin, Karel, Karla, Rath, Pent, Louise, Bartre, Nino and Athos, however, unlike the others who do not die, Merlinus will return to help in the next level if he dies. In both games, he manages the player's Supply Convoy.
