 * When going on an adventure it's hard to stay calm. As men, even if we know the adventure will be full of pain and sorrow, we still choose to go on it. Real adventures are like the ones depicted in games or comic books, they're neither easy nor quick and they can break a man's heart. Real adventures can torment people. They can make you regret ever going on them. But still, that's the true meaning of an adventure. If that's so, then why do we as men choose to go on them? Why is that? Because we want to be real men. Real men don't give up, even in front of pain or sorrow or regret! Rather, they want to live a full life. That's what real men are! With that being said, go on my son! Go to your adventure!!
 * Come forth, Sebastian!
