The night at the Inn

As I was preparing to fall asleep, I hear noises from the next room. Naturally, considering the events of the suspicious cargo, I want to check what exactly is going on.
A white haired man and a scared woodelf are comfronting a young lad, that had entered their room. Thorismund, Serebra, Kazimir are their names.
The boy tried to steal my newfound sword! Thankfully it went ablaze. The little bastard.
Suddenly, it started raining ash? A yellow light flickered in the distance, Thorismund tried to step outside.
Back inside, something weird was going on. Turns out it was an Oblex (they steal other creatures memories, assuming their forms afterwards).
