It is a Legacy probable to a Loric who come under the Lorien Star Sign Pellaren.
Henri fondly remembers how he used to make the entire house disappear as part of a prank.
Six first noticed this Legacy when her hand disappeared while she was trapped in the Mogadorian mountain base in West Virginia. She slowly concentrated on making her entire body invisible, and eventually, when the Mogadorians noticed she had disappeared and opened the cell, she slipped out, avenged Katarina's death and escaped.
Since then, Six's invisibility has proven useful in evading enemies.
As Pittacus Lore have all the Legacy, it's clear that he also have Novis.
In the Fate Of Ten, he turned himself invisible.
In United as One he uses it to turn invisible and raid a warship.
- Novis was an extremely rare Legacy as only 1% of the Garde develop it.
