The Impaler's Tomb was a virtual representation of one of Ezio Auditore da Firenze's genetic memories, relived by Desmond Miles in 2012 through the Animus.
After reading a book about Vlad Tepes and his prison from Sofia Sartor's book shop, Ezio Auditore set out to find the prison within Constantinople's Constantine District.
After free-running through a series of obstacles within the prison, Ezio found the Templar's tomb and opened it, taking out the sword contained within, before leaving through a nearby gate.
Ezio discovered and collected Vlad Tepes' Sword, after making his way through the prison that his tomb was kept in.
- Vlad's skull in his sarcophagus has long canine fangs, hinting at the story of Vlad being a vampire.
