Wizard Solo Spots for Runes

[Estu]

I have recently been soloing my wizard at the aviaks in South Karana. This is an ideal spot since I can generally single pull and root-nuke, there's a merchant right there, there are plenty of safe places to med, there is no danger of trains, and most importantly, the monsters drop runes, which I can use to craft spells.

Soon, though, this place is going to be too low level for me. Are there any other relatively safe spots I can solo in a few levels and expect runes to drop at, or would I pretty much have to go group in dungeons? I'm completely unfamiliar with Kunark, so if there are any such areas there, please be specific about where in the zone they are, whether there are friendly merchants nearby, and so on (though since I can teleport, nearby merchants aren't the biggest deal).
