Shadow magic (sorcerous origin)

Shadow magic sorcerers of the Realms drew their power directly from the Shadowfell. Their connection with that plane or the dark entities that dwelled within differed with each practitioner. Some claimed lineage from a denizen of Shadowfell while others may have directly influenced by its malign energes.

Culture
These sorcerers were viewed by some organizations as ideal infiltrators, spies, and most of all hired assassins.

Description
Whatever the origin of their connection, shadow magic sorcerers regularly manifested peculiar quirks of their behavior or character. Some individuals were entirely cold to the touch, while others rarely (if ever) bled or in some cases, blinked but once a tenday. A few particularly macabre sorcerers could not for the life of them remember there were inherent differences betweent he living and the dead.

Abilities
Shadow magic sorcerers did however have access to tremendous arcane powers. They felt quite comfortable in the darkness, armed with potent darkvision that extended outwards for and the ability to conjure darkness around them. By their nature, their existence was one that straddled both life and death simultaneously. As such, they recovered more often from mortal wounds and were exceptionally difficult to truly kill.

Those sorcerers that honed their connection to the Shadowfell and its magic could walk through shadows. This power worked similarly to that utilized by denizens of the plane and spellcasters that tapped into the Shadow Weave.

Master shadow magic sorcerers learned how to temporarily transform their physical form into that of pure shadows. While in their 'umbral form', sorcerers became highly resistance to damage and forms of magical energy (save for radiant) and could pass through solid objects as will.
