Lower hallways

In the crate harmony would find a cat with shabby, unkempt fur. Probably the pet of a former student, long since forgotten. The cat was as it seems enjoying a fat rat it had caught. It hissed when Harmony opened the crate, probably scared more than angry.

"It's alright, I'm not here to hurt you. Promise" Harmony said, putting her hand in to let it sniff.

The cat huddled, trying to make itself as small as possible in an attempt the "predator" would ignore it.

Meanwhile, harmony could hear the door of the former gymnasium open. Two people entered, one of which Harmony recognized from a previous scuff before entering this room. Both looked out for blood. Calmly they closed the door again, at least it seemed the two were egotistical enough to want to honor of capturing the escapee for themselves instead of getting reinforcements.

"Don't be afraid, i just want to leave this place, but I don't want to hurt you" Harmony whispered and tried to give it a pat.

While Harmony was occupied by the cat, the two witches who entered headed for Harmony. Abusing Harmony's lapse of attention the two used it to get some spells in.

[Toy witch]
"Chomping teddy!" she cried and a cute looking teddy bear with vicious chompers appeared trying to take a piece of of harmony... repeatedly...

[Art witch]
"Blue blob!" she intoned and where harmony was standing a blue patch of thick, greasy viscous fluid formed making the floor really slippery. It also emanated a pungent oil paint scent that would make harmony slightly lightheaded, though wouldn't negatively affect her otherwise.

Harmony looked up in a split second and turned around. She tried to run away, hoping that the cat will be ok.

When trying to bolt Harmony found the liquid to make the floor really slippery. Not only did she not get away, but with her foot sliding over the slippery surface harmony fell face first into the greasy blob, making for a slippery affair overall. At least the chomping teddy has the same difficulties making it unable to reach harmony for now.

Harmony turned over, and gasped. She slowly sat up and look at the teddy. She raised her arm and aimed at the toy.
Please let this work.... she thought as she wished for an power orb to shoot out of her palm of her hand.

The chomping teddy was blasted by the orb, and just like last time the thing was hit by a spell, it slumped a moments later faded out of existence. The toy witch started brisking and screeched: "STOP HURTING MISTER CHOMPY!" and haphazerdly launched a poorly aimed purple beam towards Harmony.

The art witch popped an almost opaque tower shield to protect herself from anything Harmony might toss her way.

"Then don't use him as a spell!" Harmony resorted, and quickly dodged the attack, "That way he won't get hurt!"

The toy witch huffed indignantly, this time aiming a bit better, especially hat Harmony's feet that were still on the slick surface. Harmony would have a poor footing after her last dodge at the moment this beam heads for her feet.

The hart user wants to join into the action and tries to cast a spell through her shield. however, the spell she launched, which somewhat resembled a blob of ink or paint collided with the shield and splattered all over the art user instead, who cursed violently in turn.

"Crap...." Haromony groaned, and "thought up" a spell to protect herself.
"Seahorse Refection" she cried quickly.

The spell Harmony needed sprang up in the clutch of time and shocked surprise on the toy witch's face as the beam headed for her face, which it hit dead center. The witch barely managed to keep standing after this hit.

The art user dismissed her stained shield and muttered some curses as she prioritized getting off the worst of the mess she herself had created off her clothes, though they looked just as ruined as Harmony's attire.

The puddle on the ground seemed to be fading, though not yet completely gone.

I have to be careful now Harmony thought, and looked around for a helpful piece of equipment that could help her out.

The puddle beneath harmony faded and in her near proximity she could find some rusty metal pipes, two-by-fours and a suspiciously well preserved gym mat, though obscured by a thick layer of dust.

In the crate near Harmony the cat that hid in it stirred, clearly upset by the ruckus happening close to it.

Without a warming the entire room seemed to groan a loud creaking noise. Harmony can detect this sound most likely stems from whatever is keeping the weathered floor from fully giving in.

ABORT!!! Harmony thought and dashed towards the crate.
"Please forgive me for this" she told the cat, and picked it up. Then she darted for the door and made her return to the upper stairwell.

Harmony managed to pick up the cat, though it protested fervently and Harmony would definitely get scratched a couple of times in the process, but to the two witches in the room Harmony was quite literally a walking free pass for the semester, and a little groaning wasn't going to stop them from getting those grades, so they did everything they could to keep harmony from fleeing, blocking the exit and pretty much launching suppressive fire in the form of a multitude of beams, which looked legitimately exhausting to keep up.

Meanwhile the floor started to groan even harder, small clouds of dust emerge from the slits between the floorboards and at last, a snapping sound could be heard.

"Love to stay and fight, but don't have time....so good luck" Harmony exclaimed and tried her best dodging the spells, protecting the cat while doing so.

Harmony ran for the exit, definitely getting hit by some beams, which would feel like getting hit with a decently thrown baseball and would leave a bruise for sure. Meanwhile a reluctant cat still tried to get away, the poor feline was frightened out of its wits and before anyone knew what was going on, the floor gave in.

When the dust settles Harmony is surrounded by a lot of debris and hinds herself in a corridor. Torches with blue glowing gems providing some kind of light.

The cat stopped protesting completely. The two witches previously launching a barrage of spells were a few meters away from Harmony. One unconscious, which by the look of her leg bent the wrong way was perhaps for the better, the other groaning but awake.

Away from the debris a narrow corridor headed in two directions, one down and one up. Both directions are illuminated with the same blue gemmed torches.

"Well, lets go up" Harmony told the cat, "I won't let you go, no matter what happens." Making sure that she was holding the cat correctly, she headed downwards.

The cat looked warily towards Harmony but then tried to lick a small superficial wound it had taken during the collapse, though the flight response seemed to have faded fully.

The two witches stayed behind, the conscious one tending to her more severely wounded unconscious friend.

Harmony entered into the corridor, almost tripping over the only crate that seemed to have survived the cave in. The cave with the new looking padlock that felt way too sturdy for the decrepit way it looked. Heading further down would be a snaking corridor of featureless corridor. Eventually Harmony would notice markings on the wall; CT with an arrow in the direction Harmony was going, and A with an arrow in the direction Harmony came from.

Harmony gulped and followed the arrow in the direction she was going.
I can do this, but I hope it's soon she thought to herself.

Harmony would follow the snaking corridor until she ended up at an iron banded heavy wooden door.

Harmony gulped and used one hand to at least try opening the door.
Man this is heavy she thought.

As soon as Harmony touched the door it glowed a bright green and zapped harmony slightly stronger than an electric fence would. "No fairies in cloud tower!" chimed a far away high pitched voice. "WE KILL THOSE," a deep demonic one followed immediately, after which a fat roaring laughter erupted along with ghostly demonic images flying out of the door's iron bars.
