History
In 2410, Cetra was assigned to the USS Ragnarok and was present during the bridge crew's first staff meeting. She was instrumental in providing history about a Verathan sub-ossemite statue which Captain Oroku Seifer activated, accidentally. She described an ancient Verathan event where massive offerings of flower pedals, native to their planet, was unloaded at one of their power-shrines. ("Department Heads")
