The town is mostly night elves, with a few tauren here and there. 

Their reactions to Halraan are… mixed, perhaps? They’re not afraid of her, per se, except insofar as she’s a powerful adventurer. Some of them are definitely uncomfortable. Most return her friendly nods, but few meet her eyes, or look directly at her at all.

He casts Voluminous Vocabulary with his arcane bond right as they start talking.  He follows it up with casting Detect Thoughts (he had it prepared simply to check for any minds, but he’s adequate enough at using it for mind reading).  Hopefully they can’t identify his detect thoughts beyond that it’s a divination.

“Hello!  This translation spell I just cast gives me grammar and vocabulary more than a full intuitive grasp of this language, so apologies if I misspeak about something.”

Voluminous Vocabulary is a bit more finicky than tongues or share language but he’s exaggerating its weaknesses.

He doesn’t even bother trying to read the undead’s mind, probably even other planetary undead still follow the rule of being immune to mind-affecting spells.  And she’s apparently a powerful adventurer and would likely block it instinctively even if it could work.  He’ll start trying to read the (elf?) woman’s thoughts, he generally needs a full 3 rounds to get any clear thoughts out of the spell, so he’ll start concentrating now.

He missed the beginning of their conversation so he doesn’t think to introduce himself.
