What is the source for that line ?...

"It is worth noting that Zahard and the 10 Great Warriors were not alone when they climbed the Tower. They had helpers, including Grace Mirchea Luslec, Quadrado, and several Princesses."

Is it a blog post ? Or something that comes from a chapter ? Or an article on SIU's blog on Naver ?
