When the party sees where the energy is coming from, the energy leaks out of a tomb nearby that took up the whole wall that had the picture of the undead on it and when it cracked open an undead dragon with a ghastly green aura that deals unholy damage every round while the dragon breathes his unholy breath giving penalties to the party; after beating the dragon the party can take the dragons skull for a shield and have it breathe the same unholy breath, after the fight the tomb collapses harmlessly around the party and a holy light fills the place healing the party and filling them with warmth.
