Marasmius, the Ecologist, resides in a cramped tent within Lake Dakhota. His focus of study is the dragonflies around the lake.
He is described as a "historically timely member" of the Achaean Ecological Society, thereby causing alarm among Elducia, Ignatius, and Arinas when he did not show up to the AES meeting held 15 Phaestian 806.
