*hits Pantalone's blunt*

I think I have a theory on Zandik's Crimson Tree. Remember the frostbearing tree on Dragonspine, wherein the tree has been tainted with Abyssal Power, having it thirst for more power as written in the tutorials and tooltips.

Perhaps this new Crimson Tree is one that thirsts for something else, upon seeing the False Sun's face. There lies in the ashes, a single sprout blossoms, an accursed red Lesser Lord if you will.

Now this is going to be headcanon/theory material from now on. Remember Alice's Spell about World Creation for Klee? Now that she's gone a bit AWOL, it might've been possible that the Mondstadtian Librarian came upon that forbidden section.

Coordinating with Nahida, they managed to preserve the Irminsul through the seed they planted with this spell. However they failed to account for the variable, Zandik and the spiteful hatred that he harbored for Yazdan as he was getting erased.

"The tree, at last, remembered that it had not died with that entombed city,

And it extended its greedy roots towards the warm ichor that irrigated the land." In the Frostbearer Catalyst description.

Just like the Frost Bearing Tree that refused to die because it consumed the crimson's essence, it bore fruit to a seedling of a world where the False Sun does not shine.

Or it could just be Evil Nahida.exe LMFAO

For this one, I suggest you go through the panels very slowly.
