The Imperial Scuttler crab was not supposed to be released to players before launch. They messed up and some did get it. I didn't even though I ordered the physical IE, just an error.Believe the explorers pack is for pre orders, has nothing to do with imperial order related items mentioned in that link.

During the Early Access period, Imperial Edition customers who have entered their 5 Day Early Access code on their account will have access to the following:
- Play as an Imperial and craft Imperial gear
- Transform any gear to look like Imperial gear
- Imperial Horse
- Rings of Mara
Customers who pre-purchased the Imperial Edition from our ESO store have no further action required, as the above items will unlock automatically for you at the start of Early Access.
After the initial 48-hour grace period that begins on April 4, customers who pre-ordered the physical Imperial Edition must enter their Imperial Pack code in the box in order to retain these items and to fully unlock the full Imperial Pack contents.
If you got the Imperial Edition you should get an in-game mail that explains what you get. And says to go to stable to purchase horse for 1g. I did and it was no problem.I see people with their white horses and so on but I can't find mine either
