Builder

"Drink from me, vampire, and use my life’s blood to kill that which I created, out of arrogance and pride. Kill me so that the Mass will die, and the Device will be destroyed!"

- The Builder

The Builder was a character featured in Blood Omen 2. The Builder was an ancient Hylden who was responsible for the creation of the Device, because of this transgression he was imprisoned in the 'timeless'Eternal Prison where Kain met him in Chapter 8: Bad Blood.

Role
The Builder was an Ancient Hylden, presumably born (or possibly created) at some point in the Vampire-Hylden war era. During the latter stages of the millenium long war, the Builder was apparently in charge of a project to create a weapon intended to end the conflict by destroying all creatures not of the Hylden race. The project created the Device and captured or created the Mass (a creature capable of killing with its thoughts), but needed a network to transmit the thoughts of the Mass onto to finish the weapon. Before it was completed however, the Builder was imprisoned in the Eternal Prison and the rest of the Hylden were banished to the Demon Realm.

The Builder languished in the Eternal Prison for eons until the Post-Blood Omen era, when Kain discovered that the Device was being used by the Sarafan Lord. Investigating the Device at the end of Chapter 7:The Canyons, Kain found the Beast contained behind Ward Gate in an upper chamber and The Beast was able to advise Kain that The Device was too massive to destroy on his own and he would require the help of the Builder - the ancient creature who had created the Device who was imprisoned in the timeless Eternal Prison.

Following the Beast's directions, Kain arrived at the Eternal Prison in Chapter 8: Bad Blood, where he fought his way to reach the Builder's cell in the heart of the prison. Lowering the cell, Kain was able to free the Builder, who crawled from the cell. When informed that Kain was seeking to destroy the Device, the Builder was eager to help. The Builder explained that the Device was a weapon constructed for use in the Elder Wars and that it functioned by channelling the mental energy of the Mass (a creature powerful enough to kill with a single thought), but it required a network onto which the energy could be transmitted which was never completed. Kain realised that the Sarafan Order (more specifically, the Glyphwrights) had completed the network in the guise of providing Glyph magic to Meridian's (and Nosgoth's) population.

The Builder informed Kain his only hope now was to destroy the Mass itself and revealed that the creature suffered from a simple weakness; the blood of the Elder Races was poisonous to it and would kill the creature. Granting the Builder the 'release' he desired, Kain killed the Builder and drank his blood, later using it inChapter 9:The Device to poison the Mass.
