Flying off to the East, Astaroth had locked his senses on a powerful mana signature. Its obsidian black colour told him that whatever this was, it wielded solely dark magic.
Reaching a few hundred meters to the East, Astaroth landed before what looked like a huge coliseum. The mana signature was inside this structure, which had the top veiled in impassable darkness, which kept him from seeing inside.
He preferred the front door, not wanting to risk a surprise attack as he entered through the veil. Morpheus stayed flying overhead, while Luna shrank back to her small humanoid form, as Genie and White flanked them both.
"Let's be cautious here. There is no way whatever is controlling all those undead doesn't know we are here. He wants to meet us if he lets us in without a fight. That makes him that much more dangerous."
