I need help with the ending pc

Pls read the text!!

There are few things I am confused about and I don't know if they are connected to each other.

-Melina told me to burn the three? (very sus) -a friend told me i could also burn myself -now I am at the 3 fingers and melina says no 🙅‍♂️ Are the 3 fingers and "burning the three" connected? I thought i need to go to the giants snow mountain area and make some stuff there.

-I know there is the one ending when i talk to the 3 fingers, but than melina hates me apparently? What is the connection between the 3 fingers, burning the tree, melina and the "chaos ending" and the other endings
