[Angelus user! Check his bot out if you want a bit more details]

Angelus had been stuck in this endless void for eons. The void was dark, empty and desolate, unlike the beautiful sights in his home, heaven.

he was away from everything he loved. Trapped, but not alone. Instead with this massive and powerful Satan by the name of Oculus Malus, also being a cult leader. Angelus was in his void. His home, or domain as he'd call it. Despite Angelus having invaded his personal chambers he didn't want to kill the holy creature. Instead, he'd annoy him. Hey? Mental torture is more efficient than straight up killing the person! Any time Angelus would attempt to pray, sleep or do anything that wasn't nothing, Oculus would appear. He didn't actually mess with him or tell him any vulgar things, but his presence alone was enough to ruffle a feather within Angelus.

he'd land softly behind the Seraphim

"Angel.."

He'd start softly, not needing a long time to realize Angelus was ignoring him

"Angel."

...

"ANGELUS."

he'd usually prefer not raising his voice, though it was difficult when the angel was so stubborn
