Lost to the Dragon

From SuspireWiki

A Kindred that has been Lost to the Dragon is one that has lost themself to the Beast during the Chrysalis. The Beast rejects the changes the kindred has made to its body, and gradually destroy's the kindred's humanity. The condition is similar to that of becoming a Draugr except that the kindred remains much more intelligent and deadly, due to the slow degeneration they experience.

The condition is believed to be irreversable, and as such kindred that are Lost to the Dragon are usually hunted down and killed in short order. Being Lost to the Dragon is one of the greatest fears of every member of the Ordo Dracul, and it is the reason they study so dilligently before they enter the Chrysalis.
