So we meet the Erueniks in Deep Circuitry, Rachell and the other inhabitants of TVR are Erueniks. After Deep Circuitry leaves Eruen, the Erueniks develop a singular culture with a singular language and a obsession with finding entertainment and stimulation that isn’t TVR. They become super afraid of all technology after being abandoned in TVR (think Dune). This entertainment involves scouring the universe for DNA for genetic manipulation. This is how they find Earth.
And while they’re scouring Earth, they cause a great disaster and destroy their planet and they all turn into energy beings with no memories. Groph in Groph’s Green Wizardry is possessed by one of these beings. Eruen is also the planet that Titus finds in Titus Waiting.
I’ve been toying with redeveloping their visual look.
