Terror Tuesday: The Thief's Confession

I've told no one these facts, but what occurred,
It felt so good I did not seek escape,
E'en as my flesh dissolved. Delight's the word
I'd use describing it. Though now I drape
My shapeless form on couches and must write
By dictating, how gladly I'd return
(If I but could), and no, I would not fight
To save myself. The reek, the rapid burn
Of its miasma have a strange allure
I long for even now, though I know well
Its consequence. The treasure is secure
While guarded by that creature! I'll not tell
Where it is found; the danger is too great.
No more adventurers should share this fate.
