The trunk had a nice lock on it, made of whatever insanely hard wood they used instead of metal. It could probably be forced by a determined thief, but the point was to not attract the attention of thieves in the first place. To that end, as soon as I was back to my tree, I started rubbing dirt on it to take the shine off. A few minutes’ attention got me a suitably grubby and time-worn trunk. Next, I harvested some dry grasses for cushioning and lined the inside.
