I am Bruno, I come from the United States, and I am from the year 2018. This is my dog, Waldo.
Now, who are you, foreginer?
Ah, Beowulf, what a wonderful name, it sounds like you have been put under Grendel's curse, and the only way to reverse it is if you kill the monster named Grendel that has been terrorizing us for 12 years.
I opened a magazine about a favorite video game of mine that takes place during this time period, and the next thing I knew, I was being sucked into a portal here.
If it means the curse will be broken and I can go home, I accept!
