~No... this isn't right,~ Lucius thought to himself, fighting back his urges.
In fact, it wouldn't be too far-fetched for him to think that this was a sort of addiction he was beginning to develop.

In the end, he decided to absorb the life force of everything else in the room - which was quite a small amount in comparison, as most of the items here had already been severed from whatever life force they had been a part of in the past.
Still, the energy was enough to take off some of the fatigue that came from using his poison earlier.
~There's nothing of value in this room,~ he thought to himself, as he searched through the final pile of materials.
