Tungsten was a member of the rogue group Unlimit, which was founded by the former Zionite, Anome. Beirn was the only surviving Unlimit left, so it would be probably to say that Tungsten is now deceased.
Although not much is known about her past life at this time, It is believed that she had a fascination with the compelling and yet-to-be-complete philosophy of life as energy. Although this idea is also accepted by the Machines, Tungsten is more for the poetic and unrigorous (or less harsh and scientific) version of the idea. She is most likely willing to discuss this to just about anyone. This could be speculated as the motive behind joining Unlimit.
- She was most likely named after a type of tough metal.
