Stuttgart, not US
"Surprisingly, [email protected] is my email address."
(last words of Avigrail, 2016)
Please note that the great Avigrail has bleedin' demised, ceased to exist. This riddler is no more! They have ceased to be, expired and gone to meet their maker. Bereft of life and rest in peace, kicked the bucket, shuffled off their mortal coil, run down the curtain and joined the bleedin' choir invisible.
