Desilu is the past, present, and future. And by representing all of time Desilu has inherited the responsibility of being the most important entity in all of existence. Naturally this means that Desilu is also the source and focal point of all sentient culture, across the universe and through infinite dimensions. Though that may seem like the least of an omnipotent collective's concerns, it is in fact Desilu's greatest pleasure. This is why Desilu has transformed into the singular form of a band, to deliver unto the unending masses the gift of Music. Not the lowercase, mortal-made, forgettable "music", but the capitalized, holy, soul-piercing, life-defining "Music."
Also, Desilu are Ewoks operating Death Stars.
