The Damned Soul

Turn around, don't look... I'm crying here like a girl, but I can't help it... I remember everything now...
My name is Ton the Windblower. My sisters and I were on an important mission, but our ship hit these rocks... I was completely alone here for three years. And I would have probably died... If some mysterious benefactor hadn't provided me with supplies and weapons!
I want to ask a favor of you...
My loneliness on the island was particularly awful because sometimes I saw it... The cursed Spark. Or rather... it found me.
They say cursed Sparks are the doomed souls of evil people, orcs, elves... But I doubt even churchmen can make sense of it all. I know one thing for certain - there's ill will in this Spark! It's a vicious enemy that knows no fear or mercy!
We might be able to leave the island. But even on the mainland, the thought that it might find me again will keep me up at night. It needs to be destroyed. Do it, and I will be able to regain my peace of mind.

Thank you. Now I can sleep peacefully.
