Tes3Mod:Tamriel Rebuilt/River Strider
These huge aquatic arthropod are bred and raised by the Telvanni to act as an alternative to boats. A large fungus is grafted to the top of their abdominal shell, living symbiotically with the animal; in that fungus a cabin for passengers is hollowed. The therionaut takes place atop the creature's head, under a small overhang supported by the strider's antenna. The antenna are coated in a fungal infection which allows the therionaut to control the strider by manipulating them. Between the head and the abdomen, a thin thorax sports four long legs and two impressive wings. While the wings cannot be used for flight, the creature can use them as sails to gain speed.
