1921

Strider looks back a century's time to see what was going down? What was 2021 the year of? What will 2021 be the year of? Strider is thinking it's gonna be aliens dude? We need something to unite us. Hopefully it's chill aliens that can teach us how to be legit. If 2020, and the first week of 2021 are any indicator... seems anything could go down.
