[@Dawnscroll] There is also the Ilunabar stuff.

On the subject of domains... EH. If you are completely lacking anything new to pick you could always do what I suggested with Amartia and pick Domains that are already kinda covered by a port but not really (Like, idk, Physics > Gravity/Balance/Entropy...). I myself will probably start to do the same, like Jewelry and Gemstones or Glass, Mirrors and Crystals or Song, Singing, Rythm and Music. Or Flora and Flowers if I ever manage to reach the point where I can take a second or third domain (nature).

Other order stuff... Hmm. Order Law, in my vision of it, would just mean Logos is extra good with law making and stuff, sounds silly when throwing it at others, but when interacting with mortals it gets its booms. Kinda what Ilunabar got with Aesthetic: An excuse to explain why mortals under her influence are so goddamn fashionable. 

So, in that sense, think more about what belongs to Logos than about what is useful. (Don't claim everything, please ;-;)
