Try as you might, you cannot escape. The entity that pursues you is not of this world.
The entity is not a person, not a creature, not something that like us that drags its physical form across the ground; no, your pursuer is otherworldly, other-dimensional. As it travels directly through the ether of existence, you have no chance to escape, but the unknown fate that it promises has delivered you into a rabid paranoiac state and you constantly, desperately, try to evade its merciless chase.
Do whatever you feel you must, but know that soon your eldritch nemesis, Reagan, will have you.
Soon you will be Reagan.
Soon Reagan is all.
Reagan as always been.
