From years of reading, I'm like 90% certain he'll die somewhere in the future. The way gramp said he ain't meeting his friend no more after this is a foreshadowing. My bet is he'll die facing whatever the thing that make he wants mc power in the first place. He'll die facing it but it didn't die in gramp hand, mc will kill it. Then the legacy continues.... Well we'll see in a year whether this is true or not lol

gramps is definitely gonna die in the later chaps LIKE ALL THIS INHERITING WILL AND ALL THAT ARE DEATH FLAGS OMG
