Rena, Jen, Paul, and Lethen sat inside the cabin, staring out the windows. They had watched as a man who looked on the verge of death had stepped out into the area of safety Rena's light magic had created. He appeared to be talking to Lucius, but the latter appeared about as interested in whatever this man had to say as a miser was towards a beggar.
An ominous feeling settled in around them as the fog thickened and surrounded Lucius once again, cutting him from view. Rena knew her spell was still active and it began draining even more magic than before. Lucius was likely still in need of any assistance he could get, so Rena simply kept funneling power into the spell.
If she increased its strength she would suffer mana deprivation in minutes, so she simply maintained it's current level. She had maybe thirty minutes until the spell failed, but she figured it was better than nothing.
