Monolith

The Monolith was an deep space research vessel created by the echidnas of Albion. Thousands of years ago, it was launched from planet Mobius to explore the local solar system. There are no known exterior images of the ship and only one interior shot of some kind of core chamber that lacked an atmosphere. The only mentioned crew member of the Monolith was an echidna named Dave who was investigating Jupiter's moon of Europa at the time. Dave's exploration was chronicled in the book 2001: A Space Odyssey. (KtE: #30)
