CROSSING WORLDS
You can argue that multiverses are part of
Genshin’s lore. Your protagonist and their twin had been travelling between worlds before they were separated and stranded in Teyvat, which is why you’re often referred to as ‘Traveller’. Eccentric Electro archer Fischl – or the Prinzessin Der Verurteilung, to use her self-applied moniker – similarly claims to hail from another world. But there’s one character we can confirm has made the leap between universes: Horizon Zero
Dawn’s Aloy (above). Whether MiHoYo is about to open the multiversal floodgates like Fortnite is debatable, though, chiefly because the Nora hunter is a freebie rather than an incentive to spend.
