Where are monster instances stored ?

[Krawbber 2]

Hi everyone , i hope someone could help me solve this puzzle.I'm trying to find where moster instances are stored, i've been searching the whole source without finding a track. I might be wrong but i think that the vid's that the monsters get during creation are temporary. Assuming that i'm not wrong, how are their informations stored and where, it has to be something that stores them individually since after relog their hp stays changed if they have been hit before a player teleports or relogs etc. I hope somebody knows.Thank you!
