Regulus didn't say anything more, but just grabbed Lily's hand and snapped them through space to land them in the dark well behind the undulating mob of undead swarming the farmhouse.

There were a few straggling undead dotting the landscape between them and the horde.

"Let's go," Regulus said and broke into a run towards that dangerous mob, trusting Lily to keep up with him.

As he ran, he sent Reducto towards any undead in range. But when they got closer, a good number of undead noticed the commotion happening behind them and turned to investigate, and then also to attack.

Now, outside of the walls of the farmhouse, he could use something far more destructive.

"Expulso!" He aimed it right at the center of the undead that had turned towards them. The whole group burst apart with blue light and the undead not caught in the center of the explosion were thrown back into the mob, bowling down undead until they lost momentum.

And it gave them a bit more room to work with. Though it did get the attention of more undead, who were regrouping and starting for them.

Regulus had to start now.

He planted his feet. "Lily, I'm going to start," he shouted towards her as a warning.

And a moment later, a flick of his wand, and a continuous stream of fire shot of our his wand at the oncoming undead. A few flicks more and the fire morphed into terrifying monsters made out of flames - serpents, dragons, chimeras. It took great concentration on Regulus' part to direct those flame-monsters towards the horde, rather than let them run amok at random. But attack the onrushing undead those flame-monsters did, igniting and incinerating corpse after corpse and rendering them piles of smoldering ruins.

It was working. For now. Regulus hoped Lily was able to do her part to keep those flame-monsters in check.
