Hella Jeff is the sweetest-ass brony in all of Eyrion. He rolls with Kraven and the gang.
Hella Jeff has been with Kraven as far back as he can remember. When Kraven was living in an inn while dealing with memory loss, he found a little cloth bundle with a baby foal inside. Kraven took care of this small pony, and named him Hella Jeff after a dream he had about stairs. After this, Hella Jeff sticks with Kraven faithfully, through thick and thin
Today, Hella Jeff is still with the party, although he feels lonely whenever Kraven leaves to go punch an Indiana Jones villain or kick the ass of a necromancer. He just chills outside and eats grass slowly, sadly.
