Sky Spirit " Sky Spirits " was the name given by the Native American tribe known as the Rubber Tree People to a race of aliens from the Delta Quadrant who visited Earth around 43 , 000 BC , imparting a genetic bonding to ancient Human s and giving rise to many Native American tribes . They appear to be warp - capable , visiting other worlds , and using power sources emitting EM reading s . They also are capable ( at least on their homeworld ) of changing meteorological conditions dramatically to create storm s with monsoon - like conditions and even cyclone s within seconds . Their entire population can be hidden using a cloaking device . They have universal translator s . They have the use of some kind of personal weaponry for defense , but nothing about these is known . While they are a society that produces technology , they use it in a manner that is in harmony with nature , such as sturdy , temporary structures for housing . According to Human accounts , they honored the land above all else . They are capable of sharing memories through touch alone . They can even harmlessly infuse other species with a portion of their genetic code by touch , and even insert a specific genetic memory that could last for several thousand years , although it would eventually fragment . This strongly suggests that they themselves also have genetic memory . It appears that they generally have brown hair that grays with age . They use the " CHAH - mooz - ee " , a healing symbol , as a blessing to the land . The species is known to have explored as far as Earth in the Alpha Quadrant . Such a journey required more than two of their generations to make it that far and would require a generational ship system . This meant that in the journey from the Delta Quadrant and back , at least two generations would never see their own homeworld . However due to their vested interest , there were apparently those willing to make the trip and this was accomplished several times over thousands of years . Connection to Humans . Visiting Earth on a journey which took them more than two generations , the Sky Spirits encountered a small group of nomadic hunters . Although the hunters possessed no spoken language or culture beyond the use of fire and stone weapons , they did have a respect for the land and other living creatures which deeply impressed the Spirits . The Spirits decided to bestow upon the hunters an inheritance , a genetic bonding so the hunters might thrive and protect their world . On subsequent visits , the Spirits found that their genetic gift brought about a spirit of curiosity and adventure , which impelled the Humans who received the gift , whom the Spirits referred to as " the Inheritor s , " to migrate away from their cold climate to the North and South America n continents over the course of nearly a thousand generations . Eventually , they numbered in the hundreds of thousands and their civilization had a profound influence on other Humans , but thousands of years later they were decimated by invaders from other lands through new weapons and disease . Those who survived scattered , many seeking refuge in other societies . When the Sky Spirits eventually returned , some twelve generations before the 2370s , they found no signs of the Inheritors ' existence and believed they had been annihilated . This story had been taught to Sky Spirits into the 24th century . In 2372 , the discovered the Sky Spirits ' homeworld in the Delta Quadrant . At first the Spirits hid themselves , believing that the Humans came to conquer them as they did the Inheritors . They furthermore used their technology to deter beaming down , and later " Voyager " s landing . The Spirits eventually revealed themselves , however , when " Voyager " s first officer , Commander Chakotay , himself a descendant of the Rubber Tree People , was able to contact them and assure them of their peaceful intentions and that the Inheritors ' descendants had survived . ( ) Chakotay attributed the blessing " Peace in your heart , fortune in your steps " to the spirits of his people . ( )
