Erik felt the fire push in, then felt the strain as he was struggling against something. Someone was going against them, pushing back against the wind. He pushed more of his effort out, following Ven and also pushing all air from around the fire. He then split his own wind, creating a second vortex outside of the fire, also dragging all air from around the fire on that side. While it was quite as strong as the one directly around them, yet it got the job done.
