Astaroth collects and sells information. He would find his secrets and reveal them to others, of he didn't harass himself. Astaroth always appeared softer, friendly, but Death knew the potential of the angel under what he showed to others.

Lucifer is in his library though he's not sprawled out in the upper level chaise like normal. Instead he is in one of the window sills with his knees pulled in. He has a book but he's mostly staring out at the garden. His mind whirling around the idea that the arrival of the celestials is only days away and he has someone around that seems desperately interested in hurting him. Though, he is glad that Dorian heeded his words about staying away.
