For anyone who wants to adopt this background story, here I provide you a list of New World characters who exist (or atleast probably exist) at that time. The names I mentioned here are in accordance with spelling from wikia.

- Inberun a.k.a Evileye (under the name of Landfall)

- Rigrit Bers Caurau (safe to assume she's capable of 5th tier magic)

- The Dark Knight, along with 10 others from The 13 Heroes, and those who related to them

- Fluder Paradyne (at that time he doesn't reach 6th tier magic yet)

- Chaindorks Vaision (Tsar) a.k.a Platinum Dragon Lord

- Other Dragon Lords

- Evil Deities

- Pinison Pol Perlia

- The party who helped and promised to Pinison (they're most likely the 13 heroes themselves, or related to them)

- Zy'tl Q'ae

- Minotaur 'Boastful' Sage (probably still alive)

- Hamsuke a.k.a Beast of the South (most likely)
