When Merklyn grants Leorix his magical totem, of the Lion, Arzon is drawn with blonde hair.
During the challenges within Merklyn's shrine, Cryotek is drawn with a red helmet rather than blue.
While Arzon questions the Bearer of Knowledge about the young maiden, his magical totem is mysteriously gone.
When Leoric raises his power staff, his glove is missing.
The narration says there are many years between the time when technology fails and when Merklynn searches for knights to give magic to. Based on the fact that Cindarr is still alive and Virulina hasn't aged, and more egregious evidence that neither have Ectar or Reekon since the "Honor Among Thieves" flashback, only a few years at most could possibly have elapsed.
