I don't have a lot to contribute here, since my Wiki-fu is significantly weaker than yours.
However, I would point out that Wikipedia's standard for this seems to be to have the "main" Sandalak page link to the current one, and have a disambiguation page, which is linked from the top of the "main" page. ("This article is about the current region of Sandalak. For other uses, see Sandalak (disambiguation).")
