Domarc, I can't think of a spot where aiming Gust of Wind would do more good than harm right now.
Domarc makes it across the floor with a graceful leap to the threshold at the end. Zangua catches his arm and pulls him through.
Mordred circles around the building to rejoin his companions at the front. The flames have found purchase on the holy house's roof; likely the entire structure will be ash by the time dawn breaks. He sees the stricken faces of the villagers gathering around the scene, and they see him too.
The last to attempt escape, Leth falls victim to the progressive failure of the support beams and floorboards. They crumble even as he springs sure-footed toward the doorway, and he plummets to the basement not far from where Felor landed.
Felor sits up, struggling to breathe and see. He hears the soft thud and grunt of Leth's impact and tries to make his way closer, but as he does so, he feels a sudden, red-hot stricture on his upper arm. He turns his head.
The shambling, flame-wreathed form of the priest is beside him, gripping him with a burning hand. The priest's head is on fire, his eyes like yellow coals, painfully bright; his mouth hangs open, retching smoke.
Felor, make a WIS saving throw. The rest of you can take an action now, except for Leth, who is disoriented and needs a moment to recover from the fall.
