Stonebrunt and Warrens

[Drawde]

These zones are part of the old world (on Odus) however they are not on my EQ CD
(Ruins of Kunark, I bought it last year) and are not downloaded by the auto-patcher.
Are they part of one of the expansion packs (Velious or Luclin?) I thought they were
"bonus" zones added as part of a patch, but if this was the case presumably they would
be auto-downloaded.
I am NOT asking for "warez" here, I'm just curious as to why I don't have these zones since
they're not part of one of the expansion continents.
