Here’s a post about Lawrence specifically
As for other OCs, It would depend on their personal experience! Let me try and describe the river a little better:
‘The River’ is a plane of existence [ or non-existence ] that is attached to Earth. It’s not heavenly or demonic, it’s just part of Earth’s natural laws and processes. It exists as ‘a between state for the dying’ or ‘one’s last moments’ although it is interpreted by those within it to be a physical place, curiously, where two beings close enough on Earth and both dying may see each other within it.
It’s generally inescapable. Despite it having no shores and endless expanse of ‘water’, it’s called ‘The River’ because it’s flowing in one direction. Depending on one’s circumstances, they may find themselves in The River where it’s shallow and the pull isn’t very strong. There is nowhere to go however, and the longer you stay, the more you forget of your life. There is a ‘tiredness’ that compels people to lie down and let the flow carry them.
The ‘water’ becomes deeper and the flow becomes stronger as one flows down The River. If one dies at peace and tired they may begin their journey here, where it’s impossible to stand back up.
Once the ‘water’ deepens and meets with the ‘sky’, The River ceases to be separate or material, and whoever was travelling it moves on from Earth to wherever they may go.
Lawrence entered The River as a child when he drowned at the bottom of a lake. He had a curiousness and love for The River and he wandered, refusing to lie down. He found a way back, which heavily violates the laws of nature.
What’s worse, is that technically, if Lawrence killed someone and went to The River himself at the same time or shortly after, he might be able to drag the poor soul back with him, violating their natural order as well.
Ashe is a Reaper. Normally their job is to cull difficult souls and keep the order of death on Earth, but he’s so fucking lazy and useless that he was sent to watch The River- a nowhere place that does not require supervision. The River operates like gravity, no one needs to enforce it. But then again, there’s always Lawrence who found something within and a way to freely leave and enter again. Ashe is aware of Lawrence’s existence but can’t do anything to stop him- much to his embarrassment and frustration. Ashe’s policy is to simply not mention Lawrence to any superiors. Much too humiliating.
