Time for a new poll swordbros! 
The temple gets a chance to be renamed because many are not a fan of the term - Grandmaster.
I suggested - The Temple of the Demon God.
@Blazing Lion suggested - The Very Very Very Strongest.
I saw someone suggested - The Temple of the King of Hell.
You are free to make your own suggestions and we will compile them into a poll and then we can vote.
