Penumbra Bloodline( Dragon Compendium)
You are descended from a planar traveler who frequented the Ethereal Plane or Plane of Shadow. The energies of these planes altered and augmented your ancestor, infusing your bloodline with a trace of shadow or ether. You are touched by the planes, and they grant you arcane powers that continue to shape your life.
Penumbra-blooded creatures tend toward extremes in coloration, with either unusually dark or fair skin, black or stark white hair, and silver or black irises. Most are very thin, but not to the point of unhealthiness. They generally wear plain clothing in subdued hues of gray or white. Creatures with shadowy or ethereal ancestry tend toward neutrality and often have quiet, secretive personalities. Many penumbra-blooded creatures prefer dark places and
avoid direct sunlight as much as possible.
Sorcerers who possess a penumbral ancestor favor spells that conceal places and people as well as spells that access the Plane of Shadow or Ethereal Plane.
Ability to cast arcane spells without preparation,
Your ancestry gives you a bonus spell known at each spell level, starting at 1st, from the following list.
4th—Evard's black tentacles
8th—Greater shadow evocation
If a character takes this feat any time after 1st level and has already learned any of the spells on this list in the class to which she applies this feat, she gains no additional spells known at those spell levels. This restriction does not apply if she learned any of these spells as a member of another spellcasting class.
Characters with this feat cannot learn or cast spells with the light descriptor, and all such spells are removed from spell lists of all their spellcasting classes.
