Hevlaska is said to be the "Guardian of the Cube" and has been part of the Black Order since its establishment. She is completely enveloped by her Innocence, which seems indefinitely invoked. She is able to "probe" inside an Exorcist's body through tentacles to touch an Innocence and determine its synchronization rate and hidden potential. She used this to confirm Cross was no longer the accommodator for Judgment from the Innocence itself. Any Innocence recovered from missions are kept within her body, which has 109 holes for each, until an accommodator is found. Hevlaska's prophesies are said to be usually correct. Source: Wikipedia
