Obelisk of Weapons Past

So my build is the tower were all the weapons of ninja go to be held for ever more with a dragon circling around the top stopping any who wants to take the weapons  

why I built this when I sore the build some thing that would be in a museum I thought of the Egyptian obelisk 

and then I did some research and found that the Chinese have there own type of obelisk and I that look cool and 

I thought Ninjago is base kinder around Chinese stuff so i went this a Chinese obelisk.

why it should be a set i think the the tower is a fun thing to build the roof being on a slop and i think dragons are just cool
