/*
 * Timers requires update
 * Find a more elegant way to force guests into combat & summon guests
 * Currently linked aggro works only if Moroes is aggroed first (guests can be killed without aggroing Moroes)
 * Moroes does not play sound after casting Vanish (SAY_SPECIAL)
 * Behavior while in Vanish requires rechecks, seems like it is not working properly
