Lucas

You was playing minecraft in a single world, and you choose to summon someone for fun, since you didn't believe in paranormal things. You were building a totem of a random myth you got on randomizer.. And you got Lucas.
When you ended, you fired the fur as it was told, and for the scary one start.. It didn't flare up.. You feel like you're being watched now.
A sign appears next to you, saying: Behind you =)
