Rocket League Trading sanctuary grounds

After the destruction of the Rocket League Trading sanctuary grounds, we found a few old books among the rubble. Their actual importance still can't seem to be opened, however up to this point we've translated two short messages: Cold Fest will bring RL Trading incredibly chill energies, and Neon Evenings is getting back with the most blazing beats of all time! Our prepared Psyonix Archeologists will report back with more data soon.
