Ly-Cilph
In Peter F. Hamilton's The Night's Dawn Trilogy, the Ly-Cilph are an alien race that evolved on an unnamed moon orbiting a gas giant planet. The unstable nature of the Ly-Cilph's homeworld's orbit meant that every nine years, the moon was consumed by violent storms. Millennia of evolution meant that even while the Ly-Cilph's corporeal bodies were destroyed, they transcended to a state of higher existence.
