Seaward
From Halopedia, the Halo wiki
G 617 g was the Forerunner designation for a planet situated within the near border reigon of the galactic halo. It was capable of supporting life, but possessed no indigenous fauna. A Primary Pioneer Group was dispatched to investigate, making a post landfull report. For one reason or another however, it failed to make a follow up report. It appears that a medium intensity military expedition was sent in after 333 hours.
Trivia
There are references to 7 in "G 617 g". "g" is the seventh letter of the alphabet and as such, 6+1+7=14=7+7
