Eta is a female elf with long puce hair and unkempt bangs above bleary, purple eyes. She frequently presents a bedraggled appearance, a consequence of her slothful activities.

Eta derives pleasure through indolent activities. She demonstrates lethargy and apathy, slowly conversing with others and moving sluggishly. Her manic devotion has helped the advancement of Shadow Garden, but it frequently manifests through petty defiance or unauthorized experimentation. Threats of budget cuts pacify her.
