Does anyone know how to summon ghosts or how to make contact with the otherworld. Also don't try to stop me.

When the moon hangs low and the winds forget their name,
By the flame that once burned and the shadow that came,
Speak thrice the vow and draw the sign in dust,
Where silence sleeps and iron turns to rust.

By blood once spilled and bone once broken,
Call forth the gate with the old words spoken.
Let no light near and no prayer be said,
For the path now opens to the whispering dead.
By ash and bone, by breath long gone, open the gate where dusk drags on.
