Here's something I wrote for one of my campaigns. If ever the "Blood for Wine" book is canonized, I'd love this to go into it :)
"Sting In The Mirror" (written for humans in Common) - to be said as final vengeance on behalf of another
Reckoning Day,
Victims say,
Could not be any... Fairer.
Your Mark found Me,
And, at last, You see,
That You invited... Terror.
Your injury to Them
Is your Ransom,
And now You shall be... the Bearer.
For You shall know
That Venom will flow
As Justice! For your... Error!
Reflect on Death!
With your last Breath!
[Insert death blow HERE, and stare into the eyes for next line]
For I AM THE STING IN THE MIRROR!
[Wait for death]
The Victim has spoken,
Vengeance awoken,
The Mirror, now broken,
By The Lady's Token
[Place the The Lady's Token (black and yellow wasp coin) and a small broken mirror on the corpse, so that all who see the corpse know never to invite vengeance]
