I got this off the Doctor Who website, which is here.
It's a script extract from The Fires of Pompeii.

THALINA
We have found it, Sister Spurrina. In the Thirteenth Book of the Sibylline Oracles. The Blue Box.
Unscrolling, revealing a crude drawing of the TARDIS.
THALINA (cont'd)
And yet, the Sibyl foretold that the box would appear at the time of storms and fire and betrayal.
HIGH PRIESTESS
...Sisters...
A whisper, from behind drapes. The 3 SOOTHSAYERS alarmed, stand, cross the room - all three moving as one - to face the drapes; they're gauze-like, lit by flames from behind, smoke in the air. A strange misshapen SILHOUETTE...

Doesn't it sound AWESOME????
And are THESE those mysterious Soothsayers?

Also in the episode are the Pyrovillains. An exclusive clip is here featuring the monster. I can't wait!!!!!!!
