A person from Arelon is "Arelene." Not sure what you'd call a Svordish person.
I believe a comment from BS recently implied that we have seen six Shards between Elantris, Mistborn, and Warbreaker. Since I can't imagine Warbreaker could possibly be portraying three Shards in its magic system(s), I think Elantris has two. The pool that dissolves Elantrians strongly resembles the Well of Ascension (which was liquid Lerasium, apparently) and is therefore probably the liquid part of the Dor's "body." Seons and Aons, I think, are the "gas" part of the Dor, and Elantris itself is the solid manifestation.
I don't think it's a coincidence that Raoden was "taken" by the Shaod when he was. I think the sentient part of the Dor was able to "choose" him for its curse in order to heal itself. I also think the chasm that injured the Dor's physical body was caused by Jaddeth (a separate Shard) in the first place.
We don't know much about Shu-Keseg (the father religion) yet, but I'll bet its followers are closer to the truth regarding the two Shards than the Korathi or the Derethi. Also, ChayShan itself strongly resembles the Feruchemy practiced by Terrismen (in that the practitioner starts out very slowly and builds up speed, strength, and momentum gradually). Aon-writing, obviously, follows after the pattern of Allomancy: something for nothing (well, no power is ever taken from living things, anyway). It's also implied that whatever Dakhor monks do requires human sacrifice like Hemalurgy. At least, there are many more hopefuls accepted than there are monks trained. Whether they die by accident in the process of their intense training or are sacrificed to create a single super-soldier is as yet unknown, but... well...
I was trying to part the post but... I really want to answer everything
First, thanks for the Arelenes one.
On the second paragraph, yes, he said we have met 6 Shards, 4 excluding Ati and Leras, and that the pool is one of the aspects we have seen.
I don't think it was coincidence on the part of Raoden, neither. In fact I was wondering if Raoden would be the one to be bound with the Dor's Shard, but then I read from BS that the children are going to be the sequel protagonists, so maybe one of them (the Elantrian, I suppose) is the Chosen One.
Probably the Chasm was caused by Jaddeth, but I'm thinking that Jaddeth and the Dor come from the same Shard, and that the Dor wis attuned to the land because it is kind of imprisoned, as Ruin was. So, Jaddeth = Dor.
There is no proof of this, but just that it would be original and ironic that the "good" and "bad" guys had the same God, and that it makes as sense as them being 2 Shards, because we have so little information.
About the magic systems....
I tried to parallel Hemalurgy and Dakhor, and it makes sense when they have to burn one monk (take into account it requires one monk, not one anybody) to teleport. But it doesn't make sense that they must sacrifice novices in order to make monks, because we have Hrathen, who left Dakhor.
Also, Aons don't get something from nothing. They really work as Allomancy, fueling something from burning the Dor.
Am I dreaming or was it written that Allomancy pure gain came from the Body of Preservation itself?
Anyway, it makes sense that, having 6 Shards and 3 Worlds/Series, and knowing there are 2 (neither more nor less) in Scadriel, there should be 2 in every other World. The only other option would be 3/1, but I can't see 3 sepparate Shards in Warbreaker or Elantris.
