- The text Lara reads in Von Croy's Apartment:
- THE SLEEPER - CUBICULUM NEPHILI - It says here, The Sleeper or Cubiculum Nephili - a stone cask. Reputed to contain the last remains of the extinct race Nephilim race. Buried somewhere in Turkey.
- From Werner's diary:
- The Sleeper or Cubiculum Nephili - literally 'sleeping cask’ or 'chamber’. Thought to be the last intact specimen of the Nephilim race. Supposedly buried in Anatolia, TURKEY.
