Lilim prefers to remain tight-lipped, but he'll perform cordiality if the situation calls for it. Not much for overthinking things, he takes situations at face value and wears very simple, easily understood emotions most of the time, but this has the unfortunate side effect of his more unpleasant emotions surfacing quite unfettered. That is to say, when something angers him, he can really have an unsightly temper.
Lilim loathes the idea of being used by others, and in this regard, he has conflicted feelings about being championed by the Scions. He feels impassive towards his Grand Company as well. He's afraid of being reduced to a mere tool and has a complex over his perceived usefulness being the sum of his worth.
