In our timeline, High Reaches Weyr will overfly High Reaches, Tillek and Nabol Holds. That means we have three major holds to play in. As well, there are countless minor holds. If you want to create a Holder, we'll be delighted and there are a couple of things we'd like you to keep in mind.
1) Holds in our timeline are very patriarchal. That means you may NOT create a Lady Holder without running it past the BOD first. You would need a very good explanation for how she became Holder over all her male relatives.
2) Holders are almost never only children.
3) As a courtesy, wives of minor holders are sometimes addressed as 'Lady'. This is a courtesy title only, and only used in a direct address.
4) Lord Holders do have trained guards. These guards are still holders, not crafters.
