How does your character's elemental power manifest? Draw or write them using their elemental powers.
Oliver's powers manifest through his history as a glassblower. Usually he uses his fire ability to create lanterns and lamps. Here he is smashing one of his glass creations. Smashing releases the firey energy of its forging. Glassblowing is a dangerous craft. Glassblowers can die of an earlier age than expected due to the strain of their art.
