For Years the Klorps, Geneticists, and Biologists from the planet Felan have been documenting every known species in the Milky Way Galaxy in their expansive archive: The Klorps Guide to Species. This Specialty 4,867,000th edition features updates to nearly all species found in previous installments of the Guide, plus the addition of two of the most exotic and fascinating intelligent Species in the galaxy, The Sludge, a Hivemind species that has been slowly spreading in the far reaches of the galaxy. And potentially the most dangerous species ever discovered and documented, Humans.
