Would Quetz be considered as related to the sun as well...? Cause you would need 9 of them teaming up with Hou'yi and a Pillar. I thought although DI happens during the EOR timelines, you can still consider to include servants who came after that - perhaps Apollo, someday.

Maybe DW will do an EOR 2.0. Who knows? I just thought with Hou'yi as a boss teaming up with 9 servants who are related to the sun would be an amazing idea. AND if a player somehow managed to kill Hou'yi before all other enemies, the shadow servants will break free of the curse and become the actual servants, restoring full HP, removing all debuffs and instantly gain full NP gauge. (i am insane if i myself cannot overcome the difficulties, i will make it more difficult for those who dares to! Lol)

Now as you stated that Assassin is female and related to the Sun... and being pre-Qin... I can't wait to see who she is!

（PS: did some research on chinese sun deities... could she perhaps be ）
