The towns seem to be the best lead he's got, but it's not nearly as solid as Gregorius would like. He questions Theodoric for basic details about the towns - the local languages, notable features, who's in charge. He also asks him whether he ever went to any of them with the previous covenant, or whether Tasia's been asking him him any questions about the area (he's not making any particular secret about the fact that he's concerned for her welfare to Theodoric).
Alongside this, he begins to pack for a trip. In the absence of any better leads, his current plan involves going to the towns and trying to find out if anyone's seen Tasia, via Posing the Silent Question if possible (but aura penalties are likely to make that tricky), via flat out asking if necessary. Unfortunately, her Leap of Homecoming means she probably won't have been staying at any of the local inns, but she might have been asking questions in them.
One other thing he does before leaving is find an excuse to be in a non-negative aura with the local wise-woman (he's been generally cultivating her over the last couple of years, so this shouldn't be too difficult). He doesn't mention Tasia's disappearence to her initially. Under the cover of their conversation, he'll drop a few Posing the Silent Questions silently and without gestures:
- What Magical Defenses does she have (the answer to this question might possibly cause him to forgo the other questions)?
- Has she been speaking to Tasia recently?
- If so, was it about anything that would cause her to head to those towns?
- What does she know about possible causes of Tasia's disappearence?
[OOC: He has a casting total of +14 with this spell, plus one level of mastery in Quiet Casting, meaning a -10 penalty for casting it silently and without gestures. He may therefore not always succeed in casting it, and is likely to be fatigued in most cases, but he probably doesn't have any botch dice. Note that the target isn't normally aware of the questioning - his intent is that she shouldn't know he's doing this. And yes, he's scrying on Tasia now, albeit he's trying to keep it fairly focussed. He's doing it this way because he doesn't 100% trust her not to be in on it.]
When packing, he deliberately only wears standard quality clothing, and generally does his best to look like a normal grog rather than a magus. He's bringing his armour and axe.
Oh well. Worth a try.
