question abt ranni questline SPOILERS

EDIT ON THE STORY I BEAT MORGOT AND THEN WENBT TO CEALID AND DID A BUNCH OF EXPLORING SO I HAVET REACHED THE LIFT OF ROLD YET SO NO SPOILS PLS







so i just finished rannis questline \[aka best one in the whole fromsoft series and on par with siegward the goat from ds3(ive only done a few so dont flame me)\] and i get the whole thing that ranni didnt wanna live like as Empyrean which was predetermined for her BUT

1 wtf is a Empyrean?

2 and are the two fingers like the greater will and kinda like a persons destiny,so ranni killed hers to escape her destiny???

2 and if im wrong abt what i said before,what are the two fingers and does everyone have a pair of two finers,bc up until now i thought only in roundtable they existed
