Echo of Blue Fire

Some plagues become endemic.

While the Spellplague ended in 1480 DR, a trace of it remains in your bloodline.  You have been exposed to a significant Wild Magic event.  This caused the plague to begin to spread inside you, ever growing with passing time.

You gain access to Sorcerer cantrips but you are encompassed in a Wild Magic Zone that always surrounds you in a 10 foot radius.
