Mehswif God of Night

Your terms are easily acceptable. I will grant your people land in my realm of eternal night. However, I must ask they pay some homage to me. They need not give you up as patron but a candle must be lit in their homes for me to extend protection over them.
I will have mine extend the same courtesy to you. A tree will be cared for in the town square and a lantern hung in its branches to show respect to you beyond not harming the earth, winds and waters.
