Clingfire is a liquid made by matrix workers that when set afire, keeps burning as long as there is some substance to burn. Clingfire will even burn stone. Evidently it is slowly exhausted or used up as it burns, because it does not simply burn all the way to the center of the planet. Arrows may be dipped in clingfire, ignited and shot, or containers of burning clingfire may be dropped from "aircars" (matrix-powered aerial vehicles). An attack of this nature by many aircars on Aldaran Castle in Stormqueen! was frustrated by Dorilys Aldaran, the titular stormqueen, who blasts them from the sky with lightning.
