The days flight across the desert is exhausting, the sun blasting your with unbearable heat. You maintain a close formation with Hehsh, who is the focus of a spell from the wizard Kolrya Honalmire which protects those nearby from succumbing to the heat. When you stray too far, the hotblooded hippogriffs immediately begin to flag, losing strength and altitude.
After the long day, you arrive at the Sharkfin Mountains, huge slabs of slate pushed into the sky by some ancient cataclysm. You climb out of the lowland desert high into the mountainous air, and the temperature drops remarkably. When you camp that evening, your mounts shivering from exhaustion and the cold, you make a fire in a shallow chasm, but the flames seem to provide little heat.
When Mordenth arrives from scouting, he uses his flame breath to heat a rock face, and things seem brighter after. You cook a small meal over your meager fire, and Mordenth lays the rest out for you.
"From here you walk. Hippogriffs are a delicacy and would be slaughtered for meat. Let us not subject the loyal beasts to such a fate. You will descend into the empire by a path, it will be obvious to find. This will take you to a mining outpost, and then to the highway south. You may need to fight to prove yourselves.
We are close to the army. To the northern capital, Ashenfall, a once abandoned orcish citadel that now is a city of the Vermillion Reavers and the Empire. You will need to infiltrate Ashenfall, avoid becoming slaves, find Veringvox, and if you can free him. If you need my help, call for it, but if I show up, every spear in the empire will turn toward us and it will be a close thing. I will be watching little ones. Fare well."
The following morning, you make your way down. It is a rough path, but soon you come upon a road of sorts, a switchback down to the mountain plateau below. You find yourself in the afternoon at the mining town, built along a set of stepped caves with only a few stone free-standing buildings. Rough characters, bugbears and orcs and goblins mostly, move sledges of rock and other goods from the surrounding mines into town. You find a tavern, carved into naked dark gray rock, but a rowdy crew of bugbears hang outside. When they see your band, they grow silent. Watching, predatory, uncertain.
