Interesting, I went close to the same place as nautical nattie and found a Behemoth and a Juggernaut a little farther out.
Here was the lvl 40 Behemoth which only gave one cargo crate >_<
Then this was the Juggernaut only a little bit away from the Behemoth. This one gave a royal chest and a cargo crate.
Then here's the one I found a little later by Padres. We got murdered by all of the other ships cause the people in my ship wouldn't stop firing at them and they came after us.
Still have yet to come across a Death Omen...
