Mini Black Holes Of Pure Evil

What about a preserved shrine, a scribed stone, a floating mini black hole ala essence of pure evil or whatever that would/could/might possibly randomly spawn in instances.
Something held together by a force of magic to work against it but now and then creates a rift to try and break free. Something that is not supposed to be found or used but has an urge, a purpose to break free and spread darkness in Wreaclast.
Using/activating one of these "mini black holes of pure evil" will create a portal or something similar of which players are either drawn into or possibly some mean shit coming out of it.

In the case of "You are sucked into the mini black hole of pure evil portal" you will end up in a unique map (no not that kind of unique, you play to much!) that is only available through one of those, here it comes again... mini black hole of pure evil portals (cant say that enough) in which you have to work as a team forward to close the rift... or whatever.

In the case of "You shouldnt have touched that now I'm releasing some mean motherf...ing shit on you" you will end up fighting nasty buggers breaking through the rift to reek havoc...reek? reak? wreak havoc? (there we go) with the purpose of...just... yeah... wreaking havoc and stuff... oh.. and yeah.. kill you all in the process. Maybe in the form of a wave/or a couple of waves of monsters comin at you with a big badass boss (unique to the rifts) breaking through the rift at the end. Kill him and you get the girl...I mean and you close the rift.

Those are two options that could be incorporated both for more variance and fun gameplay since you never really know what's gonna happen.
Am I getting sucked in?
Will I get trampled by a horde of nasties?
I dont know. Let's find out... It's ok, I have culling strike... LETS DO THIS! WAAIT!! I need to pee before we start...

This has to have some serious work done to it but I welcome everyone to share their Ideas (as long as they are serious, cause I am). This could hopefully draw us high end players out of mapping grindfests to reboot the brain with a fresh spark since, aimingly, these...yup, it's comin´ again... "mini black holes of pure evil portals" have the intention of now and then bringing something new to the table.

What do you think?

No takes on this at all?
I know it's a lot of text but it can be awesome.

bump?

And then an army of flying woodlegger (hybrid spider-woman who cast flicker strike and blood rage) and noxious woodlegger (hybrid spider-woman who cast viper strike and blood rage) breach your open rift, along with arachna maiden boss (big hybrid spider-woman who cast poison arrow, summon hatchling woodlegger, cast frenzy and cast rain of arrows) and a large chest acessible through rift after defeating all those spiders...
Well, it sounds nice, especially if happens at cruel difficulty, where actually there is no map covering it randomness.

I like it!

It can only get better :D
