@Kale (Can we use hyphens and apostrophes in our names? They are common syntax for a lot of Elder Scrolls NPC's, especially Orcs, Argonians, and Khajiit).
If the post from back in November 2013 is still valid, according to the Ask Us Anything page on the official site, yes, you can.
Question:
I remember you guys saying that you can have both a first name and a surname. Will you also take into consideration allowing a fixed list of prepositions or middle names, or do you think it’s too much? Characters like Mjoll the Lioness and Argonians have multi-word names.
Answer:
You can use more than one space in your character name, so the examples you picked are all viable. In fact, the current limit is a maximum of four hyphens, apostrophes, or spaces in total, so you can come up with all kinds of names, like Nh’yen the Ter-Grol. This should be especially convenient for players who want lore-based names for their Argonian or Khajiit!
