Selvan

The Selvan first attempted to take control of Lisa Beck's body directly by invading her dreams. Beck was able to repel the effort, forcing the Selvan to take another path. Using Walter Morales' feelings for Beck and his jealousy of Phillip Harper as a doorway, the Selvan took control of Morales, murdered Harper, and forced Beck to allow the Selvan to take over her body. (Dream Sequence, A Door Is Ajar [WAY]) The Selvan took Beck's body to Vega Two and used it to steal an artifact called the Glyph of Ranit-Del to get revenge on the Q. Millennia earlier, the Selvan species were transcending their physical forms toward omnipotence when they were intercepted by the Q. The Q Continuum decided that the Selvan were not ready to be let loose on the universe and trapped all of their consciousnesses in the metaphysical equivalent of a box. The Selvan species combined their energies into one of their number, now called the Selvan, and found a way to free him into the universe. Learning that Beck had been touched by the Q, the Selvan was determined to take over her body and use her connection with the Q and the power of the Glyph as a bridge into the Q Continuum.
