Question: Information:  - Dirk Serries (born 1968) is a Belgian composer and ambient musician. He is best known as Vidna Obmana, a pseudonym he used from 1984 until 2007.  - Vidna Obmana ( stylized vidnaObmana on many album covers ) is a pseudonym used by Belgian composer and ambient musician Dirk Serries . The name Vidna Obmana , a phrase in Croatian , literally translates to `` optical illusion '' and was chosen by Serries because he felt it accurately described the music . Serries created music under the Vidna Obmana pseudonym from 1984 until 2007 , when he official retired the name . Most of his current work is released under the Fear Falls Burning pseudonym . Vidna Obmana 's music has often been described as anamorphic and organic . He uses the techniques of looping and shaping harmonies , minimizing the configurations to a few notes . Vidna Obmana has collaborated on several occasions with artists such as Asmus Tietchens , Brannan Lane , Capriolo Trifoglio , Diego Borotti , and Steve Roach . Some of these collaborations have become entire projects of their own , such as Continuum ( collaboration with Bass Communion ) and Principle of Silence ( collaboration with Joris De Backer ) . Vidna Obmana is often cited as one of the more notable dark ambient musicians .  - A pseudonym (and ) or alias is a name that a person or group assumes for a particular purpose, which can differ from their original or true name (orthonym). Pseudonyms include stage names and user names (both called "screen names"), ring names, pen names, nicknames, aliases, superhero identities and code names, gamer identifications, and regnal names of emperors, popes, and other monarchs. Historically, they have often taken the form of anagrams, Graecisms, and Latinisations, although there are many other methods of choosing a pseudonym.  - A regnal name, or reign name, is a name used by some monarchs and popes during their reigns, and used subsequently to refer to them. The term is simply the adjective "regnal", of or relating to a reign, monarch, or kingdom, modifying "name". Since ancient times, monarchs have frequently, but not always, chosen to use a different name from their original name when they accede to the monarchy. The regnal name is usually followed by a regnal number (ordinal), usually written as a Roman numeral (VI rather than 6), to provide a unique identification for that monarch among other monarchs of that realm. In some cases, the monarch has more than one regnal name, but the regnal number is based on only one of those names, for example Charles X Gustav of Sweden, George Tupou V of Tonga. If a monarch reigns in more than one realm, he or she may carry different ordinals in each one, as they are each assigned chronologically, and some realms may have had different numbers of rulers of the same regnal name previously. For example, the same person was both King James I of England (along with Ireland) and King James VI of Scotland.  - The pope (from "pappas", a child's word for "father") is the Bishop of Rome and, therefore, the leader of the worldwide Catholic Church. The primacy of the Roman bishop is largely derived from his role as the traditional successor to Saint Peter, to whom Jesus is supposed to have given the keys of Heaven and the powers of "binding and loosing", naming him as the "rock" upon which the church would be built. The current pope is Francis, who was elected on 13 March 2013, succeeding Benedict XVI.    Given the information, choose the subject and object entities that have the relation of 'date of birth'.
