Be Eternal! The Day Prince Phil Died?

what happens

They return to Seyruun only to find the flags are at at half-mast. They think Phil (Amelia's father) is dead, but no body was recovered. They soon learn that there was (and still is) some kind of plot against Phil, which could of been why he died. While talking one late night, they are interrupted by a intruder at the castle, making the guards go into a frenzy. The next morning, Lina and the rest are attacked by the same intruder, but only to find out that it's Phil is disguise. He then reveals that the only way he could of find out who was really against him was to fake his own death. He is worried because the battle has just begun.
