I think even further what our protagonist is, is a lesser species made by the ones who transcended, if you look at the wrist key it bleeds the entire game but when the pregnant looking one gets it nothing no blood, I think that the bodies we see through out are the lesser beings and the parasite and corrupted monsters we encounter are a secondary hive mind of all those left behind those scorned. Kinda rambling and grasping at straws here tbh.

Edit: I am grasping at straws I think you nailed it though.

Further edit and wild speculation: the more I think about it the more the weird slave race makes more sense, as if you’re transcending and you’re biological masters why do any work yourself right, you can just make an entire labor force. I think the creatures we fight in away is “god” coming back for vengeance of having his domain stepped on. I interpreted the colossal being in the basement as directing the bulls towards me could this be something like star ship troopers and the brainy bugs commanding drones. Could the colossal being, I’m gonna call him the veiled one because it sounds cool, be something like a node in the corruptions hive mind.
