The Aldia Key is a key in Dark Souls II.
- Key used in the mansion of Aldia.
- King Vendrick condemned his own elder brother to the mansion.
- They both sought the truth, but through different means, and their fervor meant the eventual withering of their familial ties.
After lighting the four torches that summon the red phantoms and killing them the dragon skeleton at the start of the area will come alive, attack you and drop the key.
