Ask the corpse about himself
From Create Your Own Story
" Yeh want to know more 'bout me, eye?" The corpse asks. He seems quite uplifted to actually have someone to speak to. "I'm none tuh special in particular now, but I used tuh be quite educated in magics, y'see. 'Tis how 'm still able to talk!" He lets out some guttural laughter. "M'name's 'Obbes."
"Er...Nice to meet you Hobbes." You say, although you're not quite sure if you mean it.
" Likewise, dreamer." Hobbes replies. " T'be honest, I'dn't quite remember why I was hanged. Some o' m'brain's been eatin' by nasty insects, y'see, so m'memory s'not what it used tuh be. Anyhow, From what I do remember, I was naught but a poor magician on m'way to the Castle in the Mountain to look for work. I think t'was the people o' the Wastelands who strung me up like this."
