ok demonic portals are basically portals that demons use to transport quickly from between other demonic portals and Hell as well. demonic portals can be formed from a large number of demons that know what they're doing or a powerful demon. they range in size and the number that are in an area. if you're able to see it, basically it's like a giant mass of dark energy. i'll give you an example of what demonic portals can do with my personal experience. i worked at a night club that had many demons there anyways, it was the type of club where you would have weed, pills, coke, heroin, whatever, they had carte blanche to do whatever they wanted so that's like a paradise to demons, a Hell away from Hell. constant fighting went on when i worked there, people constantly doing drugs and drinking everytime they were opened and people constantly getting possessed whether they knew it or not. now i was of darkness at the time and i hunted demons that were rejected from Satan, working directly for Satan, the demons that were around me decided to set up a few portals in the two clubs that i worked at to increase the number of demons i could get rid of while i was at work plus i hated the two clubs anyways cuz i got paid ****. when the clubs didn't have portals they'd average about a few hundred demons a night, when the demons set up the portals there were millions of them in there when it was opened up, again a Hell away from Hell. the energy was so heavy it would make you sick if you weren't used to it and everything always seemed to move a little slower when you were around the club cuz there was so much dark energy. i averaged about 8,000 to 10,000 demons a night just working in the club and then afterwards i would chase the demons in the bad neighborhoods that were around my town cuz i know they weren't satisfied with just getting messed up at the club. the big club i worked at had three demon portals which was the one with millions of them partying in there, and i believe more are being set up in there as well so i'm wondering how long it's going to take before the place gets shut down or falls apart from violence and/or negligence. demonic portals can be set up ANYWHERE bars, nightclubs, casinoes, restaurants, houses, the woods, it doesn't matter but if your intuition is high enough you can spot a demonic portal a mile away.
