Timescape - The War Against Time, #1

Noom was nameless before he approached the planet Earth; nameless and eternal. Through an evil act of sabotage against Eternity, two creatures at the core of the Universe touched one another and unleased a cataclysmic explosion that birthed both the expanding Universe...and Time. Time did not exist in Etermity, and Noom is determined to locate it, capture it, and shove it back into the hole it came from.
So, the name: as Noom detected traces of the evil one on the planet he neared, he heard a sound emanating from one of the planet's land masses. It called to him; he felt it welcomed him to the new planet. "Noom, " it wailed, over and over again. "Noom, " he repeated. "I shall be Noom." Noom's search on Earth takes him to North Korea, Washington, D. C., and Australia, where he discovers the instrument which gave him his name. He interacts with the humanity he meets in those places and learns.
Since he is basically incorporeal, he can inhabit things, both animate and inanimate. Noom discovers some wonderful and not-so-wonderful people in his travels...and finds other Eternals on the planet, too. Are they who he seeks? If not, what are they doing on this little backwater world? Travel with Noom and find out.
