Inside of Adrian's subconscious, he was now in front of the axe psyche armament but it was still not changing form. It only means that this axe psyche armament has yet to fully accept him as its new master.
Adrian then focused all his concentration on the axe and the memories of the past owners of the axe started flooding his mind. The memories appeared all around Adrian like the whole subconscious became a giant television broadcasting the memories of the axe.
The memory that stood up the most for Adrian is the one where a man wearing the pelt of a bear with deer antlers used the axe to clear a whole area in one strike. With just one swing of the axe, the sea of trees was cleared and that area became the start of Timber Village. That man later ascended to godhood using his own strength but never left an heir.
