Hard Sign is an 861 year old letter. He is a glitchy blue hologram (which is why he is 861 years old) but doesn't indicate he's old and doesn't want to. He is only able to say: "Tvyor- ■̵̣̻̝̙͙̤̬̼͚̊̄́̆̉̾͐̌̈́̀̿̇̇̍͆̚͠͝͝͝ͅ■̵̠̒̎̋̃̽̌̈́͐̓̈͐͋͂͐͐̎͆͒■̸̳̫̖̝̼̬̰̪́̎̌͛̾͜ͅ!̷̨̛̠̦̖̯̬̹̝̿̾̏͂͐͠!̸̡̛̭͔̻̮̗̩̬͕̪̦̊̋̐͠ͅ!̶̡͙͓̣͓͖͖̯̲̼̟̟̂̚ -nak." (Translation under parentheses, some parts of some words replaced with ■̵̣̻̝̙͙̤̬̼͚̊̄́̆̉̾͐̌̈́̀̿̇̇̍͆̚͠͝͝͝ͅ■̵̠̒̎̋̃̽̌̈́͐̓̈͐͋͂͐͐̎͆͒■̸̳̫̖̝̼̬̰̪́̎̌͛̾͜ͅ!̷̿̾̏ due to a thing he has while talking.
