Jex is the pet wisp of Mireska, the Dark Willow minimap icon.png Dark Willow. It is a spherical being, pink with two arms and two wings, and its skull-shaped face is adorned on top with what appears to be a crystal. Its body consists of folds or ribs that expand and contract as it moves. Jex accompanied Mireska out of Revtel after she burned down her family estate.[1] Like Mireska, Jex is considered a wanted criminal for its actions.

A malevolent being from the Fae Realm, Jex is fond of murder, attacking his victims with bouts of arcane energy,[2] as well as terrorizing them into submission.[3] Along with its owner, Jex enjoys mischief and shenanigans.[4] Traveling in its cage, Jex has seen all the places Mireska has been to, such as Quoidge.[5]


Jex is Mireska's closest companion, and will do her bidding as well as protect her from harm.[6] Although it does not appear to speak, it is nonetheless able to communicate with Mireska through unknown means.[7] Otherwise, Jex is a sentient being with its own interests, capable of hatching plots[8], arguing with Mireska over kills and items,[9][10] and even lecturing its owner about her failures.[11]

Mireska believes Jex is her friend, but does not appear to fully trust it.[12] Perhaps for this reason, Jex is kept in a cage, and becomes enraged when it is rattled.[13] Upon seeing Viper minimap icon.png Viper, the Netherdrake that freed itself by killing its captor Pugna minimap icon.png Pugna, Mireska warns Jex not to entertain similar notions of freedom.[14]

Despite their similar appearance, Jex does not seem to be related to Io minimap icon.png Io, although there is some indication that Io likes Jex.[15]
