Presence

Description
Each presence spawns with a unique name either 5 to 7 letters long made up of randomly generated segments concatenated together. It is represented in game by the first letter of its name. Presences spawn randomly and are more likely to spawn the lower the players sanity is. When one spawns the player will remark "I feel a presence" and a bloody trail appears indicating the presence's location. The presence doesn't actually appear until within roughly 5 tiles of the player. While the presence is visible all the ASCII on screen turns bright red.

Battle info
A presence has 600 health and moves faster than the player. The best strategies are killing it with significant firepower or stunning it then breaking its line of site. The presence will despawn if the player get too far away (>24 units, not to be confused with tiles)
