The second turn. It takes place four months and two weeks before You Are Not Alone.

Kit was riding to his dad's apartment. „Oh geez. I'm late." he thought with a sigh and flicked a little rain off his jacket.
There was something he needed to resolve with other riders before going to Earth. Well, it wasn't anything for sake of both worlds, only a Christmas present for Len. A metal bat-shaped key chain.
He parked in front of the bulding and ran in, almost bursting through the doors instead of opening them. „Sorry dad, the traffice was horrible." Frank looked at his son and sighed. „You're always late. And always with that same excuse. You know you're a bad liar, Kit." The man in question shrugged. „I heard that if someone is a bad liar he can't be a bad person." His dad smiled. „That can be truth, but doesn't mean you can't tell me the right reason." Kit remained silent. He still didn't know how to explain this matter of monster, mirrors and stuff.
They sat to dinner in awkward silence.
Time was passing and late afternoon changed into evening, which turned to night. They cleaned up and prepared to sleep.
Or rather Frank did. Kit waited until he was sure his dad is fast asleep and went through mirror on Ventara. He had some uneasy feeling since evening. Something happened and he was sure it was bad. He speeded towards Rider's Base awaiting much, but not this.
The whole place was turned upside down with the bulding itself utterly destroyed.
A chill ran down his spine and Kit dove into the ruins looking for anyone or anything that could tell him what happened.
Noone. Only four decks laid in the debris. Incisor, Sting, Siren and Wrath. That could mean only one thing. Ian, Quin, Kase and Nolan were vented.
Pile of what was once inner wall moved. Kit turned around and saw Len slowly forcing his way out. He ran to his friend, throwing away the debris and pulling him out.
Wing Knight detransformed with painful sigh. His messed up state left Kit wondering what could take out probably all their best fighters.
„Len! What happened?" „I don't know. It was so fast that we barely could transform."
He begun to dissolve away. Len looked at himself, puzzled for a second. „So this is being vented." Those words would come to haunt Kit again and again. The tone was calm, almost curious, probably from shock.
Kit tried to hold him, but Len was already gone. Vented for the first time.
„No." Dragon Knight picked up the Wing Knight's deck. He wanted to cry and yell, but nothing came out.
He set out to search around again. There were no other decks, just a lot of mess and a dented briefcase lying aside, like if dropped on the run.
Kit dug inside. The damaged lock gave only weak resistance.
Inside was the Advent Key and letter seemingly written in hurry. The handwriting of Master Eubulon was still clearly recognizable.
"Kit, protect the Advent Key. Now it's up to you to use it. Be careful."
He took both and finally left the place through window of silent shop. Everything was silent as most Ventarans in nearby city were asleep. The place that was once the Rider's base stood apart, so it was likely noone noticed the battle. Noone will know what happened until tomorrow. And then?
Who knows.
