The Lion declares war on the planet and takes a small group down to the planets surface to fight an unknown enemy that seems to be the planets gods. I did get a little confused with this, but I think it was one of their first encounters with Chaos. It was eventually defeated by Zahariel.
After getting back on board their ship, Lion El'Jonson sends Luther and Zahariel back to their home world to aid with more recruiting. This seems like he is a bit cheesed off with Luther and Zahariel with what happened and with Zahariel not telling the Lion.
Here the books ends and to be honest, I was a little disappointed with the abrupt ending and no major battle happening.
You're comments and thoughts on the book if you have read it, are most welcome.
