*ahem Subtle Spell has entered the chat. Cast any spell that doesn’t require a line of sight target and that doesn’t require material components or otherwise rely on an “attack” or similar action. Like say Guardian Of Nature. Or, if you want to get REALLY pedantic: Dimension Door.
Both glowing portions are natural gas pipes. Perhaps it’s somehow ignited inside the pipes and is super heating them but also somehow NOT travelling outside the two glowing sections and burning the house down???
