Another riddle from Hargrave's notes. Can you guess which dungeon this one speaks about? As a hint, the voice speaks through a pool. First one to guess right gets a coupon for the Empcho store.
Thirteen vaults herein doth be
yet 'tis only one where lieth he:
Beware the bane that surrounds you all,
lest your own careless steps be your downfall.
This I must to all who pass!
