Visited by her "nephew" Walter Langkowski (Lily was unlikely to be an actual aunt due to her age), Gilded Lily intended to turn Walter to gold. She had done this with a great many men in the past; somehow their conversion to gold allowed her to add their life energy to her own, in effect achieving immortality. Foiled by Aurora, Lily's mask was removed in the ensuing struggle. Her mask was seemingly what was keeping her alive, on its removal, Aurora was shocked to see Lily's withered face. Lily's fur coat came undone revealing that Lily's body had been replaced with a very basic metal frame with arms, and in place of legs she had wheels, much like a Segway HT. Soon after the mask's removal, Lily died.
Her mansion became the base of operations for Alpha Flight, but in time it was shown that though her body had been destroyed, her spirit continued to surive, eventually merging with Mansion Alpha. She came to consciousness and realized what had happened to her house, using its facilities to strike back against Alpha in revenge. She could only manifest as "alchemical mists," so she used her electrical alchemy to summon Diablo from a New York penetentiary, forcing him to create a potion that would allow her to possess the body of Aurora. Aurora, however, was able to grab the potion herself and force Lily to take it, which cancelled out the potion Lily was using to sustain her own life, killing her.
