What are the descriptions of the available creatures for Summon Warlock's Ally?

Question

The D&D Compendium lists a level 9 Warlock daily power called Summon Warlock's Ally which includes the following line of description:

You summon a creature associated with your pact in an unoccupied space within range.

But nowhere in the description is the description of what pacts get what allies, or what powers those allies have. Does anyone know where in the compendium that information is or what it is in general?
