Darkness

Though Brink is very happy with his family, he can't help but let his mind go astray and think about this mysterious person Zephii had mentioned when she came back to him. This feeling leaves him far from being at ease, he worries all day and night as his wife and child do their daily normal things, singing happily or dreaming peacefully, etc. He can't help but feel like his family is in danger, even with the protection of three Spirit Beasts, he has no idea what this person is capable of, what he/she looks like, nor what their ultimate intent is.

How can Brink protect his family when there is so much uncertainty?
