Well to be honest it's all the time changing and varying. From what I've learned is that they are living in societies with are less organized, but their technologies are more advanced due to some kind of co-operation with the spiritual world, when they gain their technologies from the so called spiritual world. They can for example use slaves and they are wary that is they are all the time prepared to fight with each others and prepared to attack to anywhere, if they see a need for it. I haven't studied much how they are like to each other, but more how they are like towards Planet Earth. That is quite some explaining: I believe our planet is a special one, because this planet is special to the spiritual world as a planet where there should be the best people that is the most advanced spirit entities. And that makes us as a target to some of the et:s, due to them being jealous towards this planet. That might sound an odd reason, but it could have some truth that jealosy continually might grow anger in the et:s toowards Planet Earth.
There are always those who would like to invade this planet, if they would be able to. The only thing preventing such is the spiritual world. Such has happened in previous times according to my channeling that the hostile et:s have invaded and destroyed our planet during many ages in the past. So when they attack either they destroy the complete planet's surface and they are said to use nuclear weapons for such. But they have also smaller scale weapons, if they decide to invade and take over a planet. Then they'll use some kind of more developed weapons, which aren't invented yet by our technologies. Like the radiators and plasma cannons. The danger from them has been said to be in the time period around 2070s for some reason. I believe it's something to do with the spiritual world and how the earthlings have been towards some et races. So this is a spiritual matter, and the et:s might gain a permission during the time around 2070s to invade this planet. That is the information what I mostly get and they tend to talk about this problem between earthlings and them.
This was a short summary about the way I perceive the et:s.
