Mr. Oath Alchemist

Part 1 of Magic War Saga

My job is simple,
I go to weddings,
Use my alchemy,
Reinforce oaths.

If you break my alchemy oaths,
You will face magical consequences.
Either see Grim Reaper faster,
Or pay me better (secretly).

Once, an old friend made me swore an oath.
She told me to Live.
Even without her anymore.
Even if I cry myself to sleep every night.

So, my magic is both my blade and my poison.
I use it to cut betrayal.
I use it to cut my own heart.
I have the undo oath spell at my tips, but I can't.

I know she won't let me.
I know the spell is not the answer,
I know how to bathe in pain.
I know my oaths.
