Well, there might be an issue out near the Kaliti-Abeserrai border. Workers/Slaves have been disappearing, locals are perplexed and the monster hunters have a job set out for them. Ghivri would make a good guide for the area; Kiros too. Though he's a touch reluctant to head back to Amol-Kalit for reasons... Nothing coin can't solve
How's that sound? I've got a basic plan, but if there's anything I can add or a direction I could take things in that would suit your character let me know
To pull an idea of the top of my head; we could start with Kiros et al already in Cerak. Maybe they require horses for travel through the savanna, putting the party in touch with Dylan and bringing him along.
Basic, but it works. And can always add to it too, I'm ever flexible on details
