Hello! Olleh! hElLo! oLlEH! Hel-lo! Lo-hel! Leh-ol! Ol-hel!

 Hi! I'm Xernean, named after a Pokemon that should be fairly obvious to figure out!

I come in peace. 'U' I think. Anyway, I hope to have fun here!
By the way. No. My favorite legendary Pokemon is actually not Xerneas. It's Rayquaza. But seriously, I couldn't think of a good name while including Rayquaza.  

Sooooooo yeah. I have no idea what else to say, so here's a super-formal conclusion.

Heya, hello and welcome to the site!
Hope you'll be having fun here!
Should there be anything you do not understand or would like help with, do not hesitate to ask!

Your formal conclusion was so formal that my mind's about to explode. Heyas! I'm Celestial, and I just joined a few weeks ago. Make yourself at home at this fabulous place filled with fabulous people!
