You see nothing unusual, except for a small enchanter's glyph.
There appears to be something written on it.

In the Common language, it reads:
Nocturna

As your loresong begins, you find yourself transported to the halls of a grand palace in the dead of night. All is calm, with the gentle clinking of chainmail the only sound puncturing the silence. An armored guard rounds the corner, slouched with boredom and fatigue. Then something catches his attention: a dark puddle growing at the foot of a gilded cabinet. He moves closer to investigate.

As if in a dream, you find yourself looking through the guard's eyes as he opens the gilded cabinet. His horror overcomes you as he sees inside the dead corpse of one of his fellow palace guard, a sigil of Onar has been traced in blood on his forehead. You run your gauntleted hands across the corpse's armor and behold it has been sliced through as if it were paper. You race to the king's chambers at once.

The king is missing, nowhere to be found. The windows are open, their silken drapes fluttering in a mild breeze. A young girl cowers in the corner, terrified. You do not know her, but you approach nonetheless, seeking to comfort her, question her, anything. Your outstretched hand falls cleanly off your body. You have been disarmed! The girl fixes you with her impassive gaze, a black ora tanto gleaming in her hand.

You can no longer separate yourself from the guard. His terror overcomes you. His heart races within your chest. You feel every cut as the girl's tanto slices through your armor without trouble. Your vision is remarkably clear as you lay prostate, your life ebbing away. Amber tendrils pulse from the tanto, drawn into the girl's arm, reinvigorating her. She kneels and, using your own blood, draws what you realize mustbe a sigil of Onar on your forehead.

The harmonics generated tell you that the tanto inflicts more fearsome wounds when it strikes.
