Twisting Ruin (RP Thread)

Welcome, brave travelers. I see you've survived the perilous journey to this strange place.

These are the remains of the capital of the long-forgotten Cult of Grammar. Come, make yourself at home, as nobody knows what grand artifacts you might find, or powerful spells you might learn. Just one rule: Be grammatically correct, for you don't want to anger the Great Dictionary.

This is purely an RP thread. I am NOT trying to revive the Cult of Grammar, I am just trying to make a proper epilogue.

The first thing you notice within this ruin is a piece of paper saying "Take about 5-9 World Tree leaves and put them in water from the Elemental Plane of Water, then stir for about 2-3 minutes. After approximately 30 minutes, the tea should be ready.Oh, and don't forget to boil the water!".

What is this place?
