Looks like demigod Nico is in a pickle when the local museum acquires a new exhibit that takes over the city. If he can't solve the riddle then he's gonna join the others as permanent additions to the sphinx's servants. The riddle goes- Four letters stand to make my name, Should two be taken four remains, And if they should take away one more, My meaning will be as before. what am I? Looks like the sands of time ran out for Nico as he fails to solve the riddle. After a valiant struggle he is overwhelmed by a cursed slumber as his mind is reshaped through dreams so when he awakes he is ready to serve his Sphinx lord.
