Sent directly to earth from the Creator, to raise up their Race of Beings who have fallen prey. Things get deadly.

Fallen prey to what? Who are the Race of Beings. How do things get deadly?

One of the great things about practicing loglines; it creates healthy writing habits.

One of those habits is getting rid of unnecessary words.

Sent -- directly?('directly' isn't needed)
raise -- up (redundant, both words mean the same thing) -- However, you might want to use a different word like rally?or lead. They are sent to 'lead' their race (for instance)
race -- of beings (You don't need 'of beings', how would you have a race who were not beings?)

Finally, you have left off an important detail -- Fallen Prey... (To whom?)

Anyway, good luck with your story and keep working on this logline, the advice above is excellent

Who's the lead character?
What's the lead character's goal?
What's standing in his or her way?
