The skill says non-battle region, not sure if their HQ applies.
Can you tell how much we're playing this?
Yes, they may Teleport from HQ, which makes a Recruit + Skill action a very effective turn.
Region - Every space on the Map
HQ - A Region for scoring, but the exceptions:
-Enemies cannot enter
-No Trog tokens can be placed
Battle Region - A Region with a Battle token, i.e. Minis from two enemy combatants
Unoccupied - A Region without Minis
Controlled - A Region with a Control token
Hope that helps!
