Glitched Isekai

Sam continued watching the events unfolding from within the Nexus, sitting on a large bed with Sabrina between his legs pleasuring him with her mouth and hands and Alex sitting behind him, pressing her breasts on his back while hugging him and kissing his neck. 

He decided to keep them for backup in case any of the other two groups needed help, and also because these two were the slowest among the lot. 

"This attack by these orcs don't seem to be random do they? There are not only orcs, but also goblins, trolls and there seems to be flying creatures in the far distance. This is an army going to war!" Sam said. 

"Those are wights!" Alex said from behind him. 

"Wights?" Sam asked in a querying tone. 

"Undead" Sabrina answered as she made a popping sound releasing his cock with her mouth. 

"Look, they've gotten into trouble now" Alex pointed to the group in front. 

Selene, Annabeth, Alice and Tauriel had run and killed through these creatures without realizing it, and they started rising again right after they were run through. 

Now they were being surrounded by both the wights in front of them and those behind them that they killed. 

Only Annabeth and Selene's weapons seemed to be doing damage. Annabeth's knife was made to kill monsters so it was capable of killing these wights, but Selene's silver laced sword and silver bullets only manages to damage them and it took several hits to outright kill a wight. 

Alice looked particularly frustrated as she was used to undead zombies. But these undead wights seemed to be immune to her attacks. 

Just then, the second group burst through as Natasha, Mindy, Lara, Buffy, Faith, Hermione and Phoebe joined them and formed a protective formation. 

"These are wights! Only magical weapons have an effect on them" Hermione explained while casting a spell, but even her spells were useless against the wights. 

Besides Annabeth and Selene's weapons, Buffy's scythe and Faith's troll god hammer she borrowed from Buffy and have been using ever since were the only other melee weapons able to injure or kill the wights. 

However, as they stopped for a moment to form a defensive formation, more and more wights gathered around them, blocking all directions. 

Selene, Mindy, Natasha, Alice and Lara each aimed their guns a different direction as they started firing silver bullets with Selene supplying more whenever someone ran out. 

Buffy, Faith and Annabeth stood in between to attack anyone wight who somehow got near even through the rain of bullets. 

Alice, Phoebe and Hermione stood on standby, with Tauriel firing arrows and Phoebe and Hermione casting spells where needed, even though they were not effective at killing wights. 

Suddenly, a wight managed to burst through an area that Hermione was covering, as her spell barely slowed it down. 

By instinct, she swung her arms and a sword appeared in it, instantly slicing the wight in two. 

The other girls looked at her in amazement. 

"The sword of Gryffindor!" Hermione said happily and continued defending her section. 

"Ok, let me out again Sam. I believe I have some expertise in this" Sabrina said, standing up. 

"I think this is a battle for the mages" Alex agreed and stood up next to Sabrina. 

Sam nodded and both of them exited the Nexus, appearing within the formation the girls formed.  

"Allow me" Sabrina said as she levitated into the air and her hands started flaming. 

Instantly, all the wights as far as the eye could see burst into flames and disintegrated. 

"Let's bolt!" Mindy said and they continued running.

They ran over a hill and found that there was a town in front of them. 

There were wights standing around everywhere, and the cemetery just outside the town had hundreds of skeletons wondering around. 

It was clear that the orcs, goblins and the other dark creatures were avoiding this town as it was filled exclusively with the undead.

This town that was not too long ago filled with human lives were now completely wiped out. 

"Shall we?" Faith said getting her hammer ready.

"No don't!" Sabrina suddenly yelled

Everyone stopped to look at her.

"Can you feel it? The whole town is covered in a death aura. Most of you will die simply by entering the aura unknowingly" Sabrina said.

"Yes I can sense it now too" Alex said, casting a detection spell.

"It's very powerful" Hermione added 

"I am immune to death auras. I can scout the town" Sabrina said.

"I have some resistance to such magic too" Phoebe added.

"Ok then. You two scout while I bring everyone else into the Nexus" Sam said.

Phoebe and Sabrina walked to the town after Sabrina cast a spell rendering them undetected by the wights and skeletons. 

Before they entered the town, they saw carriage tracks that detoured and avoided the town. However, there were two crashed carriages.

As they looked around, they saw a few wights that looked familiar. There was an instructor and two students that Sam had seen but was never introduced to, and there was Heracles. 

"Cocksucker deserves it" Mindy said, as Sam nodded grimly. 

As they entered the town, Phoebe started to look pale and feel sick.

Sam immediately brought her into the Nexus.

"Are you alright?" Sam asked.

"The death aura was incredibly strong. I could feel it even through my body's natural defenses against such magic" she answered.

As Sabrina entered the town by herself, she gasped at what she saw.

In the middle of the town square were a lich sitting on a bone wyrm, with two death knights on their nightmares and a legion of undead skeleton kings!

This was an army powerful enough to destroy nations, let alone a city like Stronghold!

The more powerful beings like the lich and death knights detected Sabrina and turned towards her.

"Oh shit" Sam said just as Sabrina attacked pre-emptively.

She levitated and her hands and eyes glowed in flames as the lich, the two death knights and around 30 or so undead skeleton kings burst into flames. 

The skeleton kings started writhing and disintegrating, but the lich and the death knights seemed to be able to resist being destroyed. 

Both death knights charged forwards at Sabrina and jumped towards her.

The first knight sliced her body in two at the waist, while the other sliced her bottom half right in the middle, her pussy and ass split right in the middle.

Sabrina looked in shock, her top half of her naked body still levitating in the air, looking at her fallen legs and lower body, and her body fell from the sky. 

Sam quickly brought her separate body parts into the Nexus with the other girls bringing the parts together as fast as they could. 

Casting [Heal] on her, he looked at Sabrina, who was in obvious pain and was crying in agony. 

Her body healed and she was whole, but she was still crying. 

"Shit, we have to get out of here" Sam said, as the Nexus exit point was right in the middle of all the death knights and undead and the area was filled with death aura. 

While inside the Nexus, he looked at the distance at a hill just outside the town and ran there while within the Nexus, since he could travel distances in the Nexus to the limit of his eyesight. 

As he stood on the hill and exited the Nexus, the girls exited with him. 

Sabrina was still in his arms crying as he looked at the town angrily.

"All right girls, unleash hell!" he said.
