Aeotha knew Gershul was the biggest threat, but she couldn't attack him directly with her magic. In a way she paused simply to think over her options. Of course it was easier now that she could use her magic, but there was still the fact that immortals were immune to the effects of it. She remembered clearly when Skandra explained his race to her. A strange thing, indeed. She'd never heard of Immortals before Skandra. Perhaps she'd been too focused as a girl on the Drow and the Elves to worry about other things. She knew of humans because of great wars, and then the established treaties of Astarii and places like the Free Cities. But Immortals hadn't come up in her studies. And walking the paths she walked she hadn't encountered one, that she knew of, until she met Skandra. They looked too much like humans, except for his eyes. They always stood out as different for her.
Maybe it was just because she was particularly taken.
Still her ideas dwindled, she had the staff, but what she needed was a distraction for all those other immortals. If they were distracted then she could focus on Gershul. The risk was harming the other elves, herself, or Skandra. Direct magic wouldn't work. Indirect magic would... The idea hit her so hard she nearly stumbled just to move. The prayer quickly fired out of her lips and with her free hand she pointed, casting the spell. A line of fire emerged from the ground itself. White flames erupted and spread, as they spread they slowly changed from white to blue, to yellows and reds, the normal glow of fire. The line was drawn in the ground separating Aeotha, Líobhan, Skandra, and Gershul from the rest. It was spreading rapidly, so much that the first immortals to charge toward it didn't realize it had changed. They stepped right into it and quickly that fire spread to their clothes. Soon at least a pair of them were yelling in pain.
It would have to do. The army was too far off. Aeotha's weapon was not long range, and Líobhan was still in shock.
Aeotha turned back to Skandra and Gershul, locked together there by spear and blade. She charged across the space of grass between them wielding her staff as if it weighed nothing. She certainly wasn't about to allow Gershul to live to see another day.
