Remember, little ven…
You know Sorcery only because you learnt it while your Blood wove its way through our sacrificial altars, your throat slit.
The Blood only flows because we awakened the fire in your veins.
Shanri is not yours. It is our plaything. It is our toy, which you have stolen in our absence.
We will come back. Our curse is already upon you.
Until then, your blood entertains us.
Continue. As you were. As if the world was yours.
