Kronos was wary of the man and his ... gift, so he did not meet him in person, but sent a messenger.
The message itself was simple: "You want Cassandra. Cassandra wants me. You know how she can be defied. I know where she is. We meet on Holy Ground and exchange our knowledge. Deal?"
Yes, it was a risk, but the prospect of having Cassandra at his feet without her Voice as her defense was definitely worth it ...
Finally an answer came back. The messenger was dead. But who cared? It was done, Kantos had agreed.
As usual, not my universe, not my characters, just my story. No offence or infringement intended, no money made.
As for warnings: This contains Kronos. Kronos is Kronos. ;-)
