[He laughed for a good moment before weakly letting out a sigh.] You're most likely wondering why I haven't formed one with him. It's because there was no solid evidence of his existence besides those scriptures, most illegible due to its age. There was no way of locating him. No one had even heard of a summon spirit before until now, let alone one that had been lost in history. And so, I'm interested in finding out that history. About the summon spirit that supposedly had great influences in the creation of our world.
