Considering the situation each of her teammates where in, Sera decided which plan to follow.
'Bea is too detrimental on this side, same goes for Lucy and Will, which means it has to be plan D.'
"Everyone! Plan D is in effect! Change in 10 seconds!"
The enemy on the other side was about to hit them in 10 seconds, so Sera went in to break their momentum. Plan D relied on her the most, while Witchdoctor and Clockwork supported her from the sides and Killshot from the back.
'This is going to suck!'
She hit the wall of monsters and began cutting them to pieces, she didn't stop for a second. Stopping meant certain death.
The 10 seconds went by and everyone was at their positions, which eased her job quite a bit.
"You have killed... Your Soul is... You have... Your Soul... You... You..."
'It doesn't help, that I can hardly hear my own thoughts with this sound in my head. Fuck it's so annoying!'
She started to become angry, but held onto her sanity.
'The bloodlust would only break the formation and everyone would be swarmed.'
Sera dodged a set of scythe like appendages for the 1000th time it felt like, then delivered a devastating slash, breaking carapace and killing the monster. She was getting slower but could still keep up.
'Well, at least we are certain that there's an endless amount of these fuckers.'
While evading an attack she saw how the others were doing. Bea's side was getting worse for wear, they had some bleeding wounds, but didn't call out for retreat so none of their injuries were that bad.
On Sera's side, the tide of enemies were smaller, which made their situation better but not by much.
Sera slowly began to accumulate injuries, first it was only a small cut on the arm, then a scrape on her calf, but after a couple more minutes she had cut on every part of her body and even a few stab wounds on her thighs and side. Her wings were still as pristine as ever.
After another minute their situation worsened. The enemy redoubled their effort to eat them for some reason.
'I have a bad feeling about this.'
Suddenly she heard Bea shout.
"Retreat! Plan 2!"
'Plan 2 meant immediate retreat for everyone, while me and Bea cover the escape. If she decided with that plan, it meant something truly horrifying was heading in our direction.'
Sadly Sera couldn't really think about it since with everyone retreating, she had to turn all her attention to fighting.
Slowly Sera let the enemy capture ground and after a minute or so, she was nearly back-to-back with Bea. Her presence calmed Sera, which at this point was hard. She was reaching her limit and her bloodlust could erupt at any minute.
The retreat should've ended with Sera flying out of the sewer with Bea in her arm. It was Lucy's idea and she thought it really funny when suggesting it.
The actual execution proved to be way harder than planning it. If either of their attention slipped for even a moment, both of them would be swarmed and eaten alive.
They kept this precarious situation up for a minute then something changed. It felt like a ripple went through the air and suddenly the air became heavy. Everything stopped and everyone's movement slowed down.
'It feels like the gravity increased. It's like I'm deep under water.'
Sera looked behind her and saw Bea watching her. Then looked further behind Bea and her heart stopped.
Their at the end of the tunnel was darkness, but not like shadows or the night. No, it gave off a feeling like the deepest depths of the ocean. But that wasn't the worst. There was something in the darkness.
'I definitely shouldn't look at it. It feels like I go insane just by catching a glimpse of it.'
Instead she turned on her wing's ability on maximum power, her Essence would burn out in a couple of seconds, but that's all she needed.
Her gamble worked out and she was able to move again. Sera immediately grabbed Bea and flew out of the sewer. She didn't dare to look back even for a glimpse.
They went out through the sewer hatch, which Will instantly closed. Bea was trembling in her arm, but Sera couldn't focus on anything. All of her Essence ran out and she was doing her best to not pass out.
The others were talking including Bea, but Sera couldn't hear anything because of the constant notifications.
'Shut up! Shut up! SHUT THE FUCK UP!*
She might have said it aloud because the others gave her worrying looks, but she didn't care. The bloodlust reached its apex in the tunnels and the 'Deep Lurker' only increased it. Now she couldn't control it anymore.
Sera got up from the ground with bloodshot eyes. Witchdoctor was in front of her, probably saying some diagnosis. Sera didn't hesitate and punched her in the head, then she moved to hit Lucy but she dodged in time.
Using her momentum she tried to hit Will but his shield blocked the blow and before she could hit him again suddenly vines came from the ground immobilizing her. Bea stood in front of her, a meter or so away.
"Let me go! I'm going to kill everyone! LET ME GO!"
Screamed Sera over and over again. At some point Bea put a kiss on her brow, then Sera tried to bite her, so she moved back. There were streams of tears flowing down on her face as she whispered.
"Please... forgive me..."
With that the vines began tightening around her neck until the airflow stopped. Sera tried to hold on, but in a couple of seconds she passed out.
