"Hmm… So the fiends aren't here? Not interested," after flying around for a few minutes, I noticed these forces were formed out of Silences and locusts, with no friends.
Without friends I wasn't that much interested in dealing with these enemies. Even if they got startled by my presence, I simply led my chariot deeper, totally ignoring them.
Even if they'd bring me lots of dark realm bones, it was still pointless. I could simply clear them away using my cube, however I didn't try this out.
Such a method should be kept only for those who proved themselves immune to my threats. Or against a worthy opponent. Aside from these two conditions, it was better to keep my cube's abilities secret from the enemy sights.
The enemy was in the middle of gathering up his armies, but all I saw were the two useless races and nothing like fiends appeared for an entire day.
I kept flying around the cleared region first, then decided to move out and try to go deeper.
