Lutri

Lutri is a mischievous elemental otter from the plane of Ikoria.

This little otter once stole an arrow from the quiver of the planeswalker Vivien Reid. Through unknown means, Lutri was able to use the arrow to release a creature as if the Arkbow had shot it. By the time Vivien figured what had happened, Lutri had already vanished beneath the waves.
