Since Justice has already forgotten those days being a knight, I guess hundreds of years have passed? But how did she live so long as a human?

Besides, what about the Slave Lord? is it still the same guy or his descendant?

so i found out that justice isn't actually human, she is an elf and elf are immortal

im assuming hundreds of years have gone by, since Justice, Primrose, and the former head guard have all forgotten their lives s apart of the Elven society, as well as the Preistess has long forgotten her old life and joined a new, new religion, which also implies that We are no longer the old Slave Lord in EC 1 &2, I think were their descendant or child, since we get the futa option ahead of the game unlike EC 1 &2,  I also theorize that Zariah is the old witch's either pupil or Daughter, since they have similar featues, altho Zariah is an elf so I dont know. and ofc we never get to se Faye, Seraphine and Rhiannon anymore outside of the punishment room which might suggest that this isnt the same Slave Lord now since they're no longer the favorites kept in the Throme Room nor their own private rooms, even though in previous games they were our Prized Possesions. further implying the change in the main character. so yeah TLDR; ALOT of time has passed and I think were an all new character in the Slave Lord line.
