Pact of the Angelic Choirs is part of a series of new warlock pacts for 4E, from Adamant Entertainment.

Warlocks
treat not only with the maddening fey or strange, outré powers from the
void, but with astral creatures of light and strength. Known to mortals
as angels, most assume these creatures are messengers and servants of
benevolent deities. Some warlocks have discovered the ancient
thaumaturgies and rituals used to invoke the creatures that roam the
Astral Sea. These warlocks can channel life-giving power, or blast
their enemies with searing light and the awesome might of the heavens.

This
pact features a full listing of powers from Levels 1 through 30, two
new Feats exclusive to the pact, a paragon path, and three new magic
items.
