Here are all 5 threads:
Thread #1
Thread #2
Thread #3
Thread #4
Thread #5
I found all 5 of them linked from the top of
this Enchanter epic guide (the one you linked from the OP).
There are other threads in the same forum as well for the epic quests of other classes, you can find them just by picking different numbers at the end of the URL (e.g. 000001 is the first Bard epic thread). You can see the
full list of stuff Wayback has captured too.
