It was just a nice little stroll around the city, nothing much. However... a weird absolutely humongous skeleton guy dressed up in all the colors possible with a pretty nice glasses if I say so myself. Back to the point. He approached you and crouched down to meet you.

"hey hey broski, whadya doin' here? a lil' nice walk around de sity? das cool, bro. mind if i join?"

He seems friendly. Totally not gonna snatch your soul with an eye parasite or whatever... Anyways, you said "yes" and he immediately jumped to your side and begin both of your fabulous adventure.
