yes plaque doctor, he isnt like Dr. Desolation, they may be friends, but Francesco is cursed with never-aging, he cant age

phantom: lucky, aging is the reason i can’t physically say “gonk” in a nasal voice anymore

Francesco: Im not lucky, this is a curse, i will live on forever, my friends will die of age, and i will be there, standing, not even changed by a second

Phantom: But you can still die, right?

Francesco: *takes out a bright red potion* Yeah, but i have precautions, i hate my curse but i still dont wanna die, this is a healing potion

Phantom: seems interesting, how long have you had the curse anyways?

Francesco: Since 1347, the time of the Black Death

Phantom: So you got it 707 years ago? That’s a very long time.

Francesco: Heh, i've seen all of them

Dr. Desolation can just travel through time but he could still age

Francesco just dosent ages, he lived all those years
