"An Oath-breaker object? What's that?"
"Why, isn't it obvious? This woman was an object in helping someone break an oath. It doesn't mean that the oath is broken, but the process has definitely started. It might actually be at the last phase, in fact. Such a task leaves behind elemental vibrations that can be spotted by a Hero, you know."
"Tell me everything you know about this. Aren't oaths supposed to be fool-proof? What kind of level of a spell is required in order to break one?"
"That… Is a good question. They are supposed to be fool-proof in this age. Young King, the spell to break an oath is at the Hero level, which means that there is definitely another Empire Spirit active here. Judging from the sharp ends of the ears of the individual in front of you, I gather that we are in the Elf Kingdom?"
Daneel only grunted in response, to which Drakos replied, "Oh. Then this is definitely very troublesome."
