[Dragaera] Worlds and Planets

[Jon Lincicum]

    How many "worlds" have we seen in the Dragaera works? 

    If the Paths of the Dead/Halls of Judgment count as a separate
    "world" from the rest of Dragaera, does the East count as a separate
    "world" also?

    Since Deathgate Falls
    <http://dragaera.wikia.com/wiki/Deathgate_Falls> reside on the same
    planet as Dragaera, is it possible that the Halls/Paths are indeed
    on the same planet, but *not* on the same "world"? (Do the
    Paths/Halls perhaps exist on the head of a pin somewhere physically
    "on" the same planet, but removed from it in a metaphysical sense?) 

    We've seen the Jenoine's Place
    <http://dragaera.wikia.com/wiki/Jenoine%27s_Place>, clearly a
    separate "world" in both a planetary and a worldly sense, and there
    is the implication that The Necromancer
    <http://dragaera.wikia.com/wiki/The_Necromancer> is from a separate
    world/planet. Sethra the Younger
    <http://dragaera.wikia.com/wiki/Sethra_the_Younger> was also
    banished to what can be assumed to be a separate world/planet for
    her role in the Yendi Conspiracy
    <http://dragaera.wikia.com/wiki/Yendi_Conspiracy>. Verra's Halls
    <http://dragaera.wikia.com/wiki/Verra%27s_Halls> are clearly their
    own "world", but again, may coexist with the Halls/Paths, and could
    share the same "planet" of Dragaera with the same metaphysical
    separation. 

    It is implied that the "Old Ones" from the "Small Invisible Lights"
    of which The Last Cough from a Man with Juiner's Lung
    <http://dragaera.wikia.com/wiki/The_Last_Cough_from_a_Man_with_Juiner%27s_Lung>
    speaks in /Dragon
    <http://dragaera.wikia.com/wiki/Dragon_%28book%29>/ are colonists
    from another world/planet (presumably Terra, but never overtly
    stated as such). Teldra <http://dragaera.wikia.com/wiki/Teldra>
    mentions in /Issola
    <http://dragaera.wikia.com/wiki/Issola_%28book%29>/ that there have
    been two previous occasions during which Morrolan
    <http://dragaera.wikia.com/wiki/Morrolan> was "off the world",
    through his window
    <http://dragaera.wikia.com/wiki/Morrolan%27s_Window>. Lastly, there
    is the mention by the gods <http://dragaera.wikia.com/wiki/God> of
    another world on which Tri'nagore
    <http://dragaera.wikia.com/wiki/Tri%27nagore> still has followers. 

    There may be other examples of "otherworldly" situations in the
    books, (Vlad's encounter with an "Old Fool who paid money to tell
    him stories", for example) but it is difficult to find the real
    distinction between "world" and "planet" in all cases.

What makes a "world" and what makes a "planet" in this sense?
