Player entities are used for various kinds of warp destinations in Fromsoft games, including bonfire warps.
As a failsafe, the first player entity in a map will be used if the game has no other destination. Wrong warps exploit this. If there is no player defined, you will end up at the map origin (0,0,0).
Below is a dump of players in the game. Some of these are bonfires and marked as such.
Entries attempt to use a coordinate calculation routine to try to find the nearest landmark. Clock facing is a decimal number from 0 to 12, starting from north in clockwise order.
