Iseldis had been about to comment on her abilities to Roland, and perhaps compliment his own, but then the crypt door behind him opened seemingly of its own accord. Or maybe not, as another draugr emerged, this one wielding a bow. Lacking the time to conjure up her own again, Iseldis summoned a smaller dart of light magic, and hurled it at the draugr. It whistled through the air and pierced the undead's upper body, throwing it off balance. That was long enough for Iseldis to rush it, drawing out her staff, its white glow illuminating several feet around the priestess. When she neared the draugr Iseldis planted one end of the staff in the ground and vaulted at it, landing a strong kick to its head that knocked it back into the wall of the crypt's entrance. It was resilient, and it swiped its clawed hands at her, nearly catching her across her upper body, but Iseldis flowed backwards out of reach, twirling her staff around. She channeled her magic into it, summoning of wave of light which she launched from one end, a vertical line that cut through the darkness and then the draugr. Again as a creature of darkness it was especially vulnerable to her spell, and was burned vertically clean in two, the separate halves sliding down the stone wall to the ground. It seemed calm again, and Iseldis worked to catch her breath. Powerful though her magic was, she was yet inexperienced, and it took a lot out of her. She needed to pace herself. Still... three more draugr had fallen before them, far easier than the two back in the village. She smiled again when she turned to Roland. "Well, that brings us one step closer to-" But she cut herself off, as her attention was drawn to the ground around her. Out of the crypt leaked a black fog, lingering along the ground no higher than a foot, but thick and plainly malicious. It coiled around the leather of her boots, and tendrils of it seemed it to grasp at the ends of her robes. It didn't even seem to care for the light of the staff she'd planted in the dirt. It wasn't directly dangerous, but it was a symptom of something that sent an unsettling feeling into the pit of her stomach. "This is... worse than anything I saw at corrupted sites I was taken to as an initiate," she said to Roland, a bit of uncertainty creeping into her tone. "It's coming from inside the crypt, no surprise there. I should still be able to cleanse it, but I imagine it'll take a lot out of me." She winced. "Might need to hold back on the magic in the meantime." Little spells she could still manage without expending much, but combat magic was another matter. She restored the hovering light spell, and tilted her head towards the entrance. "Ready for this?"
