On Qalia I believe there are several areas you could be hitting for quests.

There's... gah! I can never remember what it's called... that Bunker on the Qa riverbank to the east of Khal, which has the Aukfruit and Hive quests. You won't be able to do the Hive alone, but many of the quests on offer there are soloable. One of them leads to an encampment a little ways up the plateau with a bunch of gnomes who also have quests, and another leads on to Zarabadi Landing. My 13 Bard just went there and although the opponents seem a little tough right now (mostly 15-16), I imagine I'll be spending a fair bit of time there in the next few levels.

Other than that, I believe the beacon south of Al-Hazzimat's beacon (the one between there and Aghram) has quests in your level range, including those that lead to the Temple of Dailuk, which are (I think?) mostly group quests.

Then there's the small Landing on the east side of the Qa river, which leads to ... the Refugee Camp area (?) south of it. My apologies, I've not been in the area for ages and I've forgotten what most of these places are called. The East Landing has quests around level 12, including one to go find that tent outpost which leads to further quests.

If you want to travel, Thestra has quests in that level range in Themnwar's Shield, Three Rivers, Veskal's Exchange and no doubt loads of other places I don't know about.

Hope this helps as a starting point, anyway. I'm sure others will add their wisdom.
