Ristu would be the logical choice, but Tailspinner doesn't see to be around a lot, so Grykee might be the best option. She's probably a tad more assertive than Ristu personality-wise, as well...

Garak agrees with Arriha going off to find the woodcutters, but still believes that it would be safer for Ristu to go as well, wildshaped into some flying creature. As a precaution, he casts Imbue with Spell Ability on Arriha, transferring Animal Messenger, Hold Person and Bless. Before she leaves, he will cast Status, including Arriha, Ristu and Uden in the spell's effect.
"If you get in trouble, send a messenger creature back here so we can help. These spells will help protect you and the woodcutters in the meantime."
OOC: I have changed Garak's Rogue's Gallery entry to reflect his changed spell selection for today.
