Rewards for water elementals?

[Dlw]

I'm planning on having the pcs find a small water elemental's True Name, as the arcane discovery in the Ultimate Magic book.

I'm looking for suggestions on what a water elemental might ask for as a reward for it's service.

Any ideas?

That they trow him in the ocean?
Find some mystical spring which will give him power, instantly making him at least 4 crs higher?

Rain gathered from the eaves of an arcane college. Meltwater from a remote glacier. Treasure gathered from a sunken ship. A few minutes being sprayed with a fire hos--er, a decanter of endless water.

[Brambleman]

A rod of Prestidigitation, or some item witch can also purify water.

Edit: to be honest, this is difficult for me to think of, as its only a Small elemental, larger elementals would maybe demand services that can benefit the Plane of water, so.... maybe that?

If this particular elemental has ranks in UMD, it could use stuff like a wand of create water.

It might also desire the destruction of items related to fire.

Potions, Wines, any exotic fluid...because it likes the 'taste'

[InVinoVeritas]

An alcohol elemental.

it wants to watch you defeat a noble ifriti in unarmed combat whilst completely buck naked without the help of any spells, allies or items.

just ignore the popcorn vendors and the laughter. you do have unlimited cosmic power? right?
