You are using the wrong command or the wrong arguments.

quest::movepc(zoneid,x,y,z,[heading]) - Moves the user that triggered the Event to the provided zone and loc. Heading is optional.
quest::gmmove(x,y,z) - Moves the user that triggered the Event to the provided loc.
quest::MovePCInstance(zoneid, instanceid, x, y, z) - Moves a player to an instance

Is your NPC already in PoTimeB? If so use quest::gmmove.
If they are not, then you can not just move the plaver to an instance with quest::movepc as it does not take an argument for instance id. That is what questMovePCInstance is for. I added the instance logic and put it in the fire response as an example for you. Otherwise I changed the rest to be gmmove.

my $InstID = 0;

sub EVENT_SAY {
  $InstID = quest::GetInstanceID("potimeb",0);
  if ($text =~/Hail/i) {
    quest::say("How could YOU defeat ME, $name? I have no choice but to send you to the next battle! Perhaps, you will taste death soon! Which way would you like to die? [Fire], [Water], [Undead], [Air] or [Earth]?");
  }
  elsif ($text =~/Fire/i) {
    quest::shout ("$name , go forth and DIE!!");
    quest::emote ("waves his boney finger in a circle...");
    quest::MovePCInstance(223,$InstID,-60,565,494); 
  }
  elsif ($text =~/Water/i) {
    quest::shout ("$name , go forth and DIE!! ");
    quest::emote ("waves his boney finger in a circle...");
    quest::gmmove(-60,852,494);
  }
  elsif ($text =~/Undead/i) {
    quest::shout ("$name , go forth and DIE!! ");
    quest::emote ("waves his boney finger in a circle...");
    quest::gmmove(-33,1107,494);
  }
  elsif ($text =~/Air/i) {
    quest::shout ("$name , go forth and DIE!! ");
    quest::emote ("waves his boney finger in a circle...");
    quest::gmmove(-54,1344,494);
  }
  elsif ($text =~/Earth/i) {
    quest::shout ("$name , go forth and DIE!! ");
    quest::emote ("waves his boney finger in a circle...");
    quest::gmmove(-53,1630,494);
  }
}

sub EVENT_SPAWN {
  quest::settimer("depop",3600); 
}

sub EVENT_TIMER {
  if ($timer eq "depop") {
    quest::depop();
  }
}
