Once more on Krystaran lore: names of seas and rivers?

In fact, we know not much about the world itself. Just names of some areas, like Khetar or Glacial Peaks. Are there names for rivers? Seas and gulfs? (By the way, I cannot see lakes on the map.) Mountains?

Will there ever be an update with these names? I’m sure @Sirrian named every creek on the map.
