Searching for Sounds

Hey everyone,

I have been trying to poke through things but maybe someone would have an idea of a sound effect I could use for this. It is a recurring event in my game at this point that effectively a crack in reality forms, and something happens.

I have been trying to find a sound effect for this. I based the idea a bit off of the Fate/Zero Abyss/Greater Grail scene, with that overarching dread. This is supposed to effectively be like corruption itself breaking through reality and dumping itself into the scene.

I have been looking around to see what I could find that would give that kind of feel. Whether it be here, or else where. I want to know, if you have an idea! Thanks!
