Through a mechanism known only to Bard, the "residual inspiration and thought left over" from the formation of stars were given a physical, sentient form, called Meeps. 
Little is known about the extent to which Meeps are sentient. As seen in Bard Mountain, Meeps are capable of comprehending and even dancing to the tune of Bard's song. Whether this action is a representation of their own free will or a forced ritualistic instinct is not known.
These species were only mentioned, but were never elaborated on.
