Infinite Magic (Male Reader x Harry Potter)

Trials

Hermione: We must be miles under the school.

YN: Yeah, lucky this plant thing's here, really.

Hermione: Lucky?  Look at them!

She leapt up and struggled toward a damp wall.  She had to struggle because the moment she had landed, the plant had started to twist snakelike tendrils around her ankles.  I was fine, my infinity was keeping it at bay.  As for Harry and Ron, their legs had already been bound tightly in long vines without their noticing.  Hermione had managed to free herself before the plant got a firm grip on her.  Now we watched in horror as the two boys fought to pull the plant off them, but the more they strained against it, the tighter and faster the plant wound around them.

Hermione: Stop moving!  I know what this is, it's Devil's Snare!

Ron: Oh, I'm so glad we know what it's called, that's a great help.

Ron leaned back, trying to stop the plant from curling around his neck.

Hermione: Shut up, I'm trying to remember how to kill it!

Harry: Well, hurry up, I can't breathe!

Harry fought for air, wrestling with it as it curled around his chest.

YN: It only grows in dark damp places, like caves.  Fire!

Hermione: Yes, of course, but there's no wood!

Ron: HAVE YOU GONE MAD?  ARE YOU A WITCH OR NOT?

Hermione: Oh, right!

She whipped out her wand, waved it, muttered something, and sent a jet of the same blue flames she had used on Snape at the plant.  In a matter of seconds, it loosened its grip as it cringed away from the light and warmth.  Wriggling and flailing, it unraveled itself from their bodies, and they were able to pull free.

Harry: Lucky you both pay attention in Herbology.

Ron: Yeah.  And lucky YN doesn't lose his head in a crisis.  "There's no wood!"  Honestly!

Harry: This way.

He pointed down a stone passageway, which was the only way forward.  All we could hear apart from our footsteps was the gentle drip of water trickling down the walls, until...

Ron: Can you hear something?

We listened.  A soft rustling and clinking seemed to be coming from up ahead.

Ron: Do you think it's a ghost?

YN: I don't know... sounds like wings to me.

Harry: There's light ahead, I can see something moving.

We reached the end of the passageway and saw before them a brilliantly lit chamber, its ceiling arching high above them.  It was full of small, bright birds, fluttering and tumbling all around the room.  On the opposite side of the chamber was a heavy wooden door.

Ron: Do you think they'll attack us if we cross the room?

Harry: Probably.  They don't look very vicious, but I suppose if they all swooped down at once... well, there's no other choice.

YN: I'll go.  They can't touch me.

I walked across the room, expecting the birds to dive at me any second, but nothing happened.  I reached the door and pulled the handle, but it was locked.  The other three followed me, pulling at the door as well, but it wouldn't budge, not even when Hermione tried her Alohomora charm.

Ron: Now what?

Hermione: These birds... they can't be here just for decoration.

We watched the birds soaring overhead, glittering...
