Othmir Prexus Totem: Quest Giver Ate Turn In

[Byrjun]

Looked up some random stuff by ID...

Item ID 2389 is a gate potion to Plane of Mischief (GM only?).
Item ID 1559 is a bracer from late Velious Plane of Fear revamp.
Item ID 6822 is a bracer from Plane of Mischief.
Item ID 6895 is a bracer from Luclin.

All of these would be pre-Kunark items if things were ordered like that. They aren't.

Some stuff is grouped "sorta" by relation, some stuff is grouped alphabetically like those last two examples (Mushroom Bracer, Musty Scale Bracer), it's a total mess. It's meaningless and you can't divine any sort of real information from item IDs.

Using your logic I could say that Water Dragon Meat was added in or after Velious and they just threw Sea Dragon Meat next to it because the items are so similar.

And that's probably what happened. They're all meats so they were reorganized together. Wurm Meat is a Kunark item.
