No, they did not have any idea of what trouble being a Magi could bring. Though in light of recent events they were beginning to get a fairly good idea. This couldn't be a regular occurrence for those who traveled and certainly trouble looked to follow them wherever they went. Ethan would have asked Asta to elaborate had they the time for discussion right now. This was bad, without a weapon and running on little reserves of energy as he was there wasn't much in the way of combat that could be offered on his part. Wind magic, his simple wind magic, was probably going to do nothing against opponents like these. And with no sword at his hip he had nothing to attack these creatures with aside from his ineffective spells. They had to try [i]something[/i] though, clearly this Varuna was out to get them and if they hesitated and didn't protect themselves it was going to end very poorly. 

"R-Right, I'm on it! Be safe!" Nymira was the best suited for this battle by the looks of it though Asta's magic might help turn the tables; the hounds from earlier were summoned to the battlefield and Ethan nearly doubled back to fend them off. Seeing their gazes transfixed on the Varuna however he took some solace in knowing they wouldn't be fighting a two-front struggle, reaching Nymira and Cecil instead. By now the Dimuran was gathering herself up from being swat aside and Cecil, with his gauntlets crackling audibly, rushed down their enemy. So long as Cecil could get close enough he could drive back the Varuna, they had to cover him so he could get to that point. Nymira already took it upon herself to help as she launched two fireballs at a slime and near immolated the beast, chunks of noxious liquid dripping from its body. Burning it was out of the question but with luck he could at least deter one of the creatures. Using his own magic to create a powerful gust Ethan hit the next closest slime to Cecil, uprooting it briefly and causing it to tumble aside haplessly in the wind, coming to a stop almost 2 meters from where it had begun. "Go Cecil!"

So the children weren't completely hopeless then! Fine, it made their demise all the sweeter to watch them struggle. Though its minions were being felled by the one with fire the Varuna cackled in delight as it watched the fitful battle, knowing full well it could outlast even her. "Sssssubmit! Ssssubmit and ssssurrender, I sssshall kill you sssswiftly!" it shouted, a row of discolored teeth holding a malicious grin. Oh, one of them was trying to reach him again? Eying Cecil with a perverse delight the Magi swung his staff and one of the tendrils surrounding its body swung out, trying to swat away Cecil's attack like a fly. When the mitt struck the tendril however it promptly stopped and spasmed before falling apart, the liquid unable to maintain its form under the electrical current. What kind of trickery did that boy use to disable its magic like that? No matter, it had other means of protecting itself.

The cane glowed green again as the Varuna slowly swung it side to side, four green orbs seeping into the ground at its feet. A chorus of shrill howls came out, muffled from the dirt as viscous limbs struck up from beneath, pulling to the surface liquid-beings like the ones at the river. Humanoid and bound to skeletal remains they clawed their way up, their black voids of eyes promptly turning on Cecil. "Kill! Tear him limb from limb! Die die die!" the Varuna shouted as it stomped excitably, its cane shaking in anticipation, "Our lord demands you die! Sssssstop resisting and die already!"

No one knew what Cecil's magic was or how he was able to counter the Varuna but Nymira understood how important that was for them. If Cecil could get close enough then even the defense which had kept her at bay would fall, and with that down so too would the enemy. Now that Cecil was close enough to strike however matters were complicated further as the Varuna brought even more creatures in for them to battle, the shambling corpses of the fallen acting as his tools yet again. How infuriating and utterly disrespectful to use remains in such a way, the intensity of the Dimuran's gaze upon their foe outmatched only by the intensity of her flames. Already she was breathing hard and she knew she was nearing her limits, the white hot and blue flames proving to be far too costly to use as freely as one might hope. But they had a means to put down the Varuna now and they couldn't let up. Gathering flame in the palm of her hand she compressed it into a smaller ball, throwing it at one of the new creatures. Closing her fists she then opened it and unleashed the magic she'd tossed, the flame exploding and promptly swallowing one of the creatures. Twisted howls of pain signaled the beast's demise as the liquid shell it had was melted away within seconds, the skeleton beneath proving to fair no better.
