Aberrant Dragonmark

Aberrant marks do not manifest identically each time therefore it is possible for two individuals with completely different looking marks to produce the same magical effect using the mark. Indeed each aberrant dragonmark is completely unique to its bearer. The aberrant marked are often seen as outcasts and outsiders, they are shunned by the houses if not actively hunted.
Since the War of the Mark, those with Aberrant Dragonmarks have been persecuted. It is often viewed that their mark gives them horrible destructive powers, and can lead to madness.
