Fortunately, it didn't look as if the spirit to whom Alisa had unknowingly fed her mana had anything to do with the danger it heralded. That knowledge brought her a certain measure of relief, however, she couldn't simply lay back and chill. At this time of the year, spirits issuing warnings of encroaching peril had a way of getting the living standing at attention, on the lookout for whatever might come at them. Not that the smart people wouldn't do so with or without warning, but alas, the added motivation was there anyways.
She needed sleep though... She had a long day, doing just about every mission she could pick off the request board and carrying them out in about as close to record time as a mage her level possibly could. Which was pretty damn fast mind you, but that only meant she'd need an extra time for sleeping, and even a complete knowledge that she could theoretically go look for the spirit again once the clock hit midnight didn't really do anything. In the end, a vain woman like Alisa couldn't go without her beauty sleep, for she knew fully well just how much sleepless nights could prove hazardous to her skin.
Though Alisa found it a fair bit harder to get some shut eye with all the spiritual warnings and signs of impending danger, she fell asleep eventually like the calm, cool beauty she was deep down. In the end, she fully understood she needed herself at full power to deal with whatever it was the mysterious ghost had warned her about, and also how she wouldn't really feel like leaving town until she had done so. For all her nature as an aloof wanderer, she still felt a certain measure of professional responsibility - of pride in doing something she could look back on as a job well done - and wouldn't abandon that feeling so easily.
But in the end, whatever she believed mattered little. While she was fully capable of falling asleep even with her mind preoccupied with such matters, external forces had completely different plans for her, and wouldn't really allow her said beauty sleep to begin with it. She couldn't even tell how long she had slept before she started getting wierd, almost prophetic dreams that didn't really stop until she woke up, sweaty and short for breath, and not even in the good way... She wiped all the sweat off her face and rose upright, looking around sleepily until she found the time. Three AM... It wouldn't do to be walking around at this time, but she'd felt this calling before, two separate times already. That spirit needed her once more, and she doubted it had any considerations for approprite times for sleeping. Being dead, it could just sleep whenever...
"Let's go, Lumen.", she asked, waking up her partner with a determined but smooth voice, putting on her work outfit, grooming her hair, then putting on her headband.
