Sacrifices - ideas?

[Ktulu]

Not sure if this is the proper place..

In my current campaign, the heroes will learn of a ritual that binds a deity to a person (and their followers). This is the ritual that created the Yuan-Ti, Galeb Duhr, and Paladins, among others.

The ritual will provide immortality and power so long as the caster willingly commits routine sacrifices to fuel the ritual (it also weakens the god of death, but that's beside the point).

Anyway, I'm looking for some interesting suggestions for sacrifices. Currently:

The Yuan-Ti ritual required poisoning their sacrifice, then bleeding them out and drinking "The blood of Zehir".

The Paladin ritual required sacrificing one's life, love, and duty in service to Pelor (my paladin deity).

I have two others that need to be explained in different means before I continue with the campaign. Any suggestions?

Galeb Duhr (in my world, they're actually former humans who cannot control the power given. Those that can become Titans) - looking for something that explains a sapping of the "primal" powers of the land

The Winter Wolf (similar to the galeb Duhr, only those who pray to the winter totem, rather than the earth).

Are you ok with the subject sacrificing his own body?

Galeb Dur - In an elaborate ritual the subject is buried alive in the mother of the earth. The figure is reborn as a Galeb Dur. Or is he?


Winter Wolves - Die of winter exposure beneath a moonless sky to wake among the pack with the new moon. The figure is wrapped in funerary blankets and left beneath an auspicious tree. The subject removes the blankets saying prayers with each one. Finally they fold the blankets and bury their civilized ways beneath them. They turn into the winter wind and wait to be taken.

Sounds pretty good. That should work pretty well for the both of them.
