Donestre

Donestre are bizarre semi-humanoid monsters from European medieval legend and mythology, unlike almost all other monsters and demons envisioned in these particularly superstitious times the Donestre stands out as actually showing deep remorse over their actions, yet are doomed to repeat them in a twisted kind of psyche play - as such the Donestre is seen as a symbolic beast created to embody the fear of travellers in foreign lands who felt themselves becoming changed by the "alien" cultures they came in contact with.

As such Donestre were depicted as humanoid lions who would welcome travellers to their land and befriend them only to quickly turn homicidal and devour their victim in a frenzy, leaving no part of the body left save for a severed head - which the beast would proceed to stand over and mourn, despite being the one responsible for their former "friend's" violent demise.
