Seraphina derives from the Hebrew seraphim, often translated as "the fiery ones," referring to a high order of angelic beings associated with burning devotion. The name is commonly read as carrying intensity and ardor -- passion understood as a kind of luminous energy rather than something to be tempered or subdued.
In matters of secrecy, let not the Moon be combust, but going from combustion. - William Lilly (1602.-1681.)
