Dredged up from the chaotic mires of the Abyss, the glathaxus horrors that spawn when summoning spells go awry are hard to categorize. They’ve been known to vomit forth into existence, attack, flee and sometimes even aid those that called them into the material plane by accident.
With being able to sprout feathers to fly, grow bladed limbs to kill and chatter dozens of languages at once - with each sentence contradicting the last, the glathaxus is better off killed on the spot, lest it escapes and spoils the sane world.
