Briar/Brier would be ブライアー (Buraiaa) or ブライヤ (Buraiya). Again, Br names typically (assuming not always) use a "Bu" character.

I still think the above suggestions about Bariesol, Barisol, or its other equivalents is best right now. I've checked in with a Japanese source who I know is crazy about figuring out these name origins and she too is in a similar slump of there being numerous variations (which this discussion's already thrown forward) that would probably require mothy or a booklet/CD's confirmation of its proper English spelling.

This situation is very similar to Kiril's name where there were numerous spellings for that and we ended up having to change our spelling once the Act 2 CD confirmed it.
