Xaphan

Xaphan - One of the apostate angels, now a demon of the 2nd rank.  When Satan and his angels rebelled, Xaphan joined them.  Warmly welcomed because of his inventive mind, he suggested to the rebels that they set fire to Heaven; but, before the idea could be carried out, Xaphan and his colleagues were hurled to the bottom of the abyss, where Xaphan is (and presumably will be) forever engaged in fanning the embers in the furnaces.  His emblem is a pair of bellows.  For a likeness of Xaphan see De Plancy, Dictionnaire Infernal, 1863 ed.  (a)

Xaphan, a second-order demon, kept the fires of Hell stoked and blazing.  At the time of the angels' rebellion, it was Xaphan's suggestion to set Heaven on fire.  (c)
