Yes, that is correct.

I see the 01 93 in the packet when he was picked up during zone in. I am guessing this in no way reflects his ID of 202081 - Merabo_Sotath (Brewing Supplies). Sorry I am trying to wrap my head around all of this.

202081 is just his id in the PEQ npc_types table, which is never sent to the client and has no meaning to it.

0x0193 is the entity_id.

Entity_ids are assigned sequentially, starting from 1, to each NPC that is spawned in a zone, so the first NPC to be spawned gets EntityID 1, the next one gets 2, etc, etc. These are what are sent in the OP_ZoneEntry and various other packets and are what tie things together in the packets.

The EntityID an NPC get assigned could change depending on the order things get spawned, so you need to look at the OP_ZoneEntry packet in the particular collect your are looking at to see what it has been assgined.

The EntityID of an NPC is the 32 bit value following the null terminated name string at the start of the OP_ZoneEntry packet.
