Risei's heart stalls, then flares up until the arteries in his neck protrude from his skin with every burst. The cold is unbearable, holds him frozen up to the thigh, and it's all Risei can do to open his circuits and call on his ability to heal so that he doesn't lose the leg entirely. But that healing is confined to his skin, and if anything the expansion of his flesh makes the ice even more painful.

The car drives away, skirts the pool of black ice and takes off back into the forest. A slap of slush floors over the bike and Risei's legs, adding insult to injury and compounding the thickness of the ice. He'll never be able to get the bike out on his own now, no matter the magic, but he has to survive first--

The flare casing. That first. If Risei pulls himself up from the snow he can just barely reach it. He does, cracks the top and sets one flare alight and rams it into the snow beside him in case he passes out. The next, he brings closer to the ice around his leg, carefully strafes it until the ice begins to melt. He can spare enough magic to warm his body and speed this along, but only that, and he mostly just twists and pries, millimeter by millimeter, until the ice chips and the circumference is wide enough escape.

It takes nearly an hour to free his leg. If not for his healing magic he would have died of exposure fifteen minutes ago.

And he still has a long ride--no, walk--back to the church.
