Eiden's role, traits, and development

Adaptable, openly affectionate, practical, and comfortable discussing desire, Eiden uses empathy and humor to connect companions from very different cultures and factions. He channels magical essence, forms contracts, and supports combat through gem resonance, although individual gameplay skills vary by card and event version.
