Unexpected Boundaries

The two unicorns were caught completely off guard by the hydra as it got nearer and nearer. With some quick thinking from Twilight, the ponies were teleported out of harms way as a massive foot crushed only their fire. All four heads zeroed in on the ponies and one opened its giant maw. Star jumped in front of Twilight and Maple as a powerful blast of water escaped it. Star had put up a shield but the forceful stream of water was quickly eroding it away.

"Take Maple and run." Star commanded as he put up another shield. Twilight's eyes showed signs of hesitation but she did as she was told. Maple was on Twi's back and they ran into the forest. Now to focus on the problem at hoof, Star thought barely avoiding the blast that had broken through his shield, and buy them as much time as I can.

Twilight was dashing through the forest as quickly as she could trying to get away from the monster that Star was distracting. A bright flash of blue came from behind her followed by a pained roar. She felt her heart skip a beat as she came to a stop.

"What's going on?" Maple asked as she started to wake up.

"I'm going back, I can't let him fight alone." Twilight replied as she did a 180 and dashed back towards the hydra.

Star was thanking whatever had shot that blue arrow, for it had saved his life.

"You okay down there?" An unfamiliar voice asked him from behind.

The hydra had been temporarily dazed by the flash of light but had finally regained its senses which it expressed with a royally ticked off roar. A red maned blue unicorn jumped out of a tree revealing herself to Star.

"What can you do?" She asked Star.

"Shields and restraining magic." He replied not letting the hydra's heads out of his sight.

"Can you give me a clear shot to one of their heads?" Star replied with a nod as he shot a chain which smashed into one of their heads causing them great pain. The middle head opened its mouth again as he attacked with the continuous spray of water. Star had put up his shield again but was quickly becoming fatigued from all of the magic he had expended. Several bursts of violet light blasted each head once each causing them to once again cease their assault.

"I've come to help." A worried Twilight said dashing over to see if Star was alright. He was out of breath but otherwise unscathed.

"Can you get a clear shot in the mouth?" Star asked the blue unicorn.

"Sure, just present me with the target." She said pointing to the bow on her flank.

They had no more time to talk, as one of the heads decided to try to snap them up. They all jumped out of the way in time, not noticing that the rest of the heads had decided to blast them to kingdom come.

"Watch out!" Star shouted knocking Twilight and Maple to the ground as the blue pony let out a yelp. All three blasts that were aimed at Twilight forcefully blasted Star into a tree behind them. The blue unicorn didn't let this opportunity go to waste as she launched three arrows simultaneously, watching them all burst into flames once they impacted their target effictively burning the inside of their mouths. Everypony was startled, even the hydra, but Twilight poured all of her strength into a magical shockwave that knocked the hydra off his feet. The hydra fell to the ground with a thud that shook the entire forrest, and thus the hydra was now safely immobilized. Twilight payed this no attention as she ran over to help her injured friend.

"Are you okay?" She asked Star who hadn't moved an inch. Upon closer inspection Star wasn't as damaged as he first appeared. The powerful spray of water had removed a patch of fur the size of a watermellon and it was aparrent that he'd broken a leg due to the collision with the tree, but that was the extent of the damage.

"Daddy? Please wake up." A teary eyed Maple begged her father who continued to lay unmoving on the ground.

"Don't worry Maple. Daddy's just sleeping. He'll wake up in a few hours." Twilight said trying to comfort the filly.

"You promise?" Maple's voice had gotten quieter as she stared up at Twilight with big watery tear filled eyes. She nodded gently pulling the scared filly into a much needed hug.

"That was awesome, is he still alive?" The unicorn asked walking over, causing Twilight to stare daggers at her and hug the worried filly even tighter.

"He'll be awake in a few hours. But he broke his leg." Twilight said with a sigh of relief, as Star let out a tiny groan.

There was a pause before the unicorn spoke again, "Well that was awesome, Taking a direct hit from equestria's third most wanted criminal and living to tell the tale. That takes some skill. My name's Erza by the way." Twlight barely listened to what Erza said because she was too busy using a healing spell in a feeble attempt to fix Star's front leg.

"You guys look like you could use some muscle. At least until you can get back on your feet. Want some help?" She offered.

"Thanks, we need all the help we can get." Twilight smiled happy that they were lucky enough to meet a kind and powerful pony in their hour of need.

Twiilight levitated the unconsious stallion onto their back as they began to look for a new place to camp. However both Maple and Twillight failed to notice the fact that a member of their party had been straggling behind.

There was a blue flash as the hydra ceased all movements and a light blue sphere escaped their mouths before flowing into their new home, a blue unicorn with a fiery red mane.
