"I only saw the end of it through my servants eyes.  Assassin and her master were fighting Caster, his master, and another man.  Assassin was badly hurt, so her master ordered her to use her noble phantasm. Casters master commanded his servant to do the same thing, but Assassin finished first. Assassin charges, the unknown man charges and seals her in some kind of enclosed space with him, and then they're both gone. Nothing left but scorched earth where they met. It appeared to be a suicide attack. We left, not wanting to engage in battle before the start of the war," Riley summarizes, not too happy to recall the past events.
