Those 2 zones are the "preview zone" from the quests introducing DoF (though it is only now that I noticed them). Quest starter can be found at Antonica/Commonland near the bell dock and finish in an instanced zone where you can find a Bootstruter guide book to Desert of Ro.
I used those 2 zones as a training map beginner, but as I could not use Inkscape (which caused fatal error on my computer), I used the online SVG generator. But as I could not find any others SVG viewer (the IE one is awful), I just posted the log files.

It is funny to notice the name of the zone/boat, which is maybe a leftover from the devs of this good old eq1 underwater area (Phinny, where are thou!)
