So ive been trying to remember this book series for the last couple of months and have had no luck. I cant remember any character names or locations but ill list everything i know! I read it in high school so anywhere between 1990 to 2014 were the publication dates, but it probably wasnt released that long ago nor ended in 2014.
1)it is not the world of tiers series or nights dawn trilogy, but has aspects from both. The fantasy side from world of tiers, but instead of different floors with different "worlds/ecosystems", its different dimensions/universe. And the invaders from the higher dimensions can come to our dimension because they can see below their dimension, whereas we can go to their dimension with the help of magic to help us see, but without it we would become mad from the bright colors. I cant exactly remember what dimension they come from, but i think its either the 5th or 7th. The nights dawn trilogy comes into play because in the third book, there is a being called the sleeping god. In the series im trying to remember, there is a god that needs to consume other beings because its always thirsting for power, and i believe the gods followers get their powers from him.
2) the opening of the first book is a magician has a dream of the sea, and it quickly becomes a storm. He sees a warrior race from a higher dimension coming to kill them all in the 3rd dimension.
3) besides the opening of the first book, i dont remember anything else other than a few details like they have to use magic to disguise themselves as the people from the higher dimension, and the last book has them at their capitol so they can infiltrate the castle to destroy the god below.
4) this probably wont help but its the last piece of information i have. Now dont laugh, but there is a certain part in one of the books where from the perspective of one of the beings from the higher dimension (he his prophesied to help kill the god). But basically its a small fight scene where someone grabs his arm, so he pulls down on his hand while simultaneously sweeping his leg behind the guy to knock him to the ground. While falling, he grabs the guys throat and slams him to the ground. I thought this was so badass so i memerized this move..... you know .... just in case ;).
Any help would greatly be appreciated as it was one of my favorite books while in high school.
