[Strategia_In_Ultima]

Have you had other intelligent and/or sentient races present on your planet as of yet? I do not only mean UFO sightings, abductions and the other male cow excrement that people say are alien, but also; did another intelligent and/or sentient race evolve on Lenthos next to you? If so, are they still present or are they gone, be it due to cause of diseases, war with themselves, war with you, their taking off to another planet in a cryogenic tank-equipped interplanetary/interstellar space ship?
