His magic had already swept a rocky circle around the pillar clear of ice, forcing it back and raising it up into a wall with two openings.  For simple dwellings he called and shaped more ice within the boundary away from the flame, forming crude huts that could be lined with snow and fur for insulation.  The fabric of the former tents could be reused for other things, and it was less than an hour before he had icy "houses" - closer to smooth, square igloos - formed atop the rock in the clearing.  They were no more special than the tools, but they would keep off the wind and hold heat better than the open air.
