The Ending [Reveled][Major Spoilers]

[Doffy90]

God this is confusing.

In the end it seems that Philip finds out that the Tuurngait is nice and take sides with it and therefor tell us to kill some other caves or something (hence the coordinates). But now suddenly he betrayed them? How did he betray the Tuurngait? As I mentioned I think he sided with it and then it wouldnt be his downfall. Its very confusing.
