"I remember the first time I saw you at the Academy. You reminded me of myself. A scientist ready to forge a new vector of experimentation. But sometimes we venture too far. No great science should ever put lives in danger." Heimerdinger is an empathetic mentor with a love for science and education. While he cares a lot about the safety of his people, his near immortality and PTSD caused by the Rune Wars cause him to act rashly in response to anything related to magic, even when it can save lives. His trust in most people and his ironic naivety caused him to be somewhat complacent, as he was mostly unaware of the corruption in the Council or the brutality of the enforcers in Zaun. He was both a typical wise elder who was ignored by corrupt politicians and a traumatized child who needed therapy. He was too focused on potential dangers to see the present issues. Due his immortality and already advanced age, Heimerdinger tends to take things far too slow for human standards, always insisting the development of technology to be dealt slowly, suggesting decades of careful experimentation and overly safe measures, leading more than once to the frustration of fellow scientists who don't have such ludicrous lifespan to dedicate so much time to their goals.
