Here were some of those old system messages, i just found in an old archive I didn't have in the logs:

You can only sneak on dry land.

Some confirmation here:

Hide works just fine in Kedge. Unfortunately, Sneak doesn't work at all. You get the message, "You can only sneak on dry land." Rogue stealth is completely negated in this zone.

Mention of rogues being able to sneak through Cazic-Thule sewers in era:

All in all, I really liked my time in Cazic-Thule. Learn the zone. As a rogue, sneak/hide to the various camps and ask to join in person instead of over shouts. People are more likely to let you join them when you are already there and haven't brought a train to them.

Some other roguely notes: getting to the gator pools requires a swim down a well. If you're swimming skill is high enough, you can sneak/hide swim to get in and just barely make it before drowning. You cannot however make it back out, as swimming up seems to be slower than swimming down. This usually means turning off sneak inside the well in order to pop out at the top. If you are too low a level, this will aggro the lizzies at the top of the well and you will have to make a run for it. Alternatively, you can get a magical invis or enduring breath for this.

The AoF is also reached through the water. For a rogue, the best way to sneak in is through the long tunnel that leads to the top of his bubble, but you will just frustrate yourself trying to get out that way. To get out, you can sneak out the back door, through the sewers, and swim up a well into the main courtyard. Again, this swim is just a little too long to sneak through and you might have to make a run for it when you pop out of the well.

You must be on dry land to fish.
